1 Introduction

Composite laminates have many advantages such as highspecific strength high specific stiffness and good fatigueresistance Because laminated materials are often made intothin-walled structures they are prone to large deformationunder various external loads resulting in nonlinear dynamiccharacteristics that exhibit complex geometries Undercertain excitation conditions harmonic resonance mayoccur which also has a significant impact on the accuracy ofthe structure -erefore it is necessary to analyze thenonlinear harmonic resonance characteristics of laminatedcomposite plates

Although the nonlinear vibration characteristics ofcomposite structures have been studied for many yearsresearch on the free vibration of laminated plates and shellstructure still retains the attention of many scholars Wanget al [1] quoted a refined plate theory (RPT) with a newpolynomial shape function to establish the displacementfield of the middle core layer of sandwich laminates and the

conditions and static boundary conditions Khdeir andReddy [12] solved the vibration equation of laminated platesby using the state variable method Litewka and Lew-andowski [13] studied the nonlinear vibration of Zenerviscoelastic plates Eslami and Kandil [14] studied the forcedvibration of rectangular laminated composite plates sub-jected to harmonic excitation Amabili [15] derived thenonlinear vibration equation of a rectangular plate by usingthe Lagrange equation Delapierre et al [16] studied thetransverse nonlinear vibration of isotropic uniform annularthin films subjected to uniform transverse loads Kumar et al[17] carried out the nonlinear forced vibration analysis of anaxially functionally graded inhomogeneous plate Chen et al[18] put forth the numerical solution of the nonlinear vi-bration of an arbitrary prestressed plate-e large amplitudeforced vibration of thin rectangular plates made of differentrubber materials was studied experimentally and theoreti-cally by Balasubramanian et al [19]

Nonlinear vibration of the laminated plates exhibitsdifferent characteristics with the change in boundary con-ditions Studies on thin plates having different boundaryconditions provide the following results An analysis of thenonlinear dynamics of a clamped-clamped FGM circularcylindrical shell subjected to an external excitation anduniform temperature change was presented by Zhang et al[20] Bennett [21] studied the nonlinear vibration of anti-symmetric angle-ply laminated plates Rafiee et al [22]studied the nonlinear vibration characteristics of simplysupported functionally graded material shells under com-bined electrical thermal mechanical and aerodynamicloading Kattimani [23] studied the nonlinear vibration ofcomposite plates and hyperbolic shells with simply sup-ported or clamped boundary conditions -e nonlineardynamic response of piezoelectric functionally graded ma-terial plates with different boundary conditions resting onPasternak-type elastic foundations in the thermal environ-ment was studied by Duc et al [24] Mohamed et al [25]used a new numerical method to study the effects of axialloads imperfections and nonlinear elastic foundations onthe natural frequencies and forced vibration characteristicsof beams Cho et al [26] studied the vibration of rectangularplates with circular holes and stiffeners mounted on elasticdevices by using the energy-based assumed mode method

Internal resonance is also unique to nonlinear systemsand is different from linear systems Internal resonance willoccur when the two natural frequencies of the system satisfya certain relationship -e unique internal resonance phe-nomenon of the nonlinear system will excite the originalnonexcited modes due to the energy transfer between themodes Nayfeh and Mook [27] studied the dynamic char-acteristics of discrete and continuous systems under dif-ferent resonance conditions Nonlinear vibration of acomposite laminated cantilever rectangular plate with one-to-one internal resonance under in-plane and transverseexcitations was studied by Zhang and Zhao [28] -enonlinear vibration behavior of carbon nanotube reinforcedcomposite plates and piezoelectric rectangular composite

laminates under parametric and forced excitations wasstudied by Zhang et al [29 30] Chang et al [31] studied thesubharmonic responses of rectangular plates which areharmonically excited with one-to-one internal resonanceZhang et al [32] studied the nonlinear transverse vibrationsof in-plane accelerating viscoelastic plates in the presence ofprincipal parametric and 3 1 internal resonance

Secondary resonance is a phenomenon particular to thenonlinear system which includes superharmonic and sub-harmonic resonance Many scholars have studied the sec-ondary resonance of nonlinear systems -e subharmonicresonance of FGM truncated conical shell under aerody-namics and in-plane force is investigated by the method ofmultiple scales by Yang et al [33] Nonlinear subharmonicresonances of the current-conducting thin plate in elec-tromagnetic field are studied by Hu and Li [34] Li and Guo[35] studied the subharmonic resonance of both ends of acomposite laminated circular cylindrical shell in a subsonicair flow under radial harmonic excitation by using themethod of multiple scales Jomehzadeh et al [36] investi-gated the nonlinear subharmonic resonances of graphene-matrix composite to the harmonic -e primary sub-harmonic and superharmonic responses of a fractionalviscoelastic plate are studied by Permoon et al [37] and asimilar research has been conducted for cylindrical shells byAhmadi and Foroutan [38] Hosseini et al [39] investigatedthe nonlinear forced vibrations of a viscoelastic piezoelectriccantilever in the cases of primary resonance and non-resonance hard excitation including subharmonic andsuperharmonic Naprstek and Fischer [40] studied the superand subharmonic synchronization effects of the van der Polequation on harmonic excitation It is found in the litera-tures that most of the researches on subharmonic resonancesare focused on the conservative systems having a single-degree-of-freedom system

In this study the subharmonic resonance characteristicsof a two-degree-of-freedom laminated composite platesubjected to transverse harmonic excitations are investi-gated -e innovation of this paper lies in that the nonlinearvibration modeling of the thin plates with arbitraryboundary shapes and boundary conditions and the non-linear vibration of the plates under different boundaryconditions can be studied by assuming the correspondingmode function -e rectangular plate with simply supportedboundary condition studied in this study is only a specificcase when the boundary shape is determined and theboundary is acted on by no external force In the absence ofinternal resonance the low-order and high-order modes areuncoupled and so they are studied separately Based on thetheory of higher-order shear deformation plate and vonKarmanrsquos geometric relationship the nonlinear dynamicequations are established by using Hamiltonrsquos principle -eordinary differential equations for the vibration of therectangular plate were derived by two-order discretizationusing the Galerkin method-emultiscale method is appliedto obtain an approximate solution to the resonance problemBoth the amplitude-frequency response equation and the

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Nonlinear vibration of the laminated plates exhibitsdifferent characteristics with the change in boundary con-ditions Studies on thin plates having different boundaryconditions provide the following results An analysis of thenonlinear dynamics of a clamped-clamped FGM circularcylindrical shell subjected to an external excitation anduniform temperature change was presented by Zhang et al[20] Bennett [21] studied the nonlinear vibration of anti-symmetric angle-ply laminated plates Rafiee et al [22]studied the nonlinear vibration characteristics of simplysupported functionally graded material shells under com-bined electrical thermal mechanical and aerodynamicloading Kattimani [23] studied the nonlinear vibration ofcomposite plates and hyperbolic shells with simply sup-ported or clamped boundary conditions -e nonlineardynamic response of piezoelectric functionally graded ma-terial plates with different boundary conditions resting onPasternak-type elastic foundations in the thermal environ-ment was studied by Duc et al [24] Mohamed et al [25]used a new numerical method to study the effects of axialloads imperfections and nonlinear elastic foundations onthe natural frequencies and forced vibration characteristicsof beams Cho et al [26] studied the vibration of rectangularplates with circular holes and stiffeners mounted on elasticdevices by using the energy-based assumed mode method

Internal resonance is also unique to nonlinear systemsand is different from linear systems Internal resonance willoccur when the two natural frequencies of the system satisfya certain relationship -e unique internal resonance phe-nomenon of the nonlinear system will excite the originalnonexcited modes due to the energy transfer between themodes Nayfeh and Mook [27] studied the dynamic char-acteristics of discrete and continuous systems under dif-ferent resonance conditions Nonlinear vibration of acomposite laminated cantilever rectangular plate with one-to-one internal resonance under in-plane and transverseexcitations was studied by Zhang and Zhao [28] -enonlinear vibration behavior of carbon nanotube reinforcedcomposite plates and piezoelectric rectangular composite

laminates under parametric and forced excitations wasstudied by Zhang et al [29 30] Chang et al [31] studied thesubharmonic responses of rectangular plates which areharmonically excited with one-to-one internal resonanceZhang et al [32] studied the nonlinear transverse vibrationsof in-plane accelerating viscoelastic plates in the presence ofprincipal parametric and 3 1 internal resonance

Secondary resonance is a phenomenon particular to thenonlinear system which includes superharmonic and sub-harmonic resonance Many scholars have studied the sec-ondary resonance of nonlinear systems -e subharmonicresonance of FGM truncated conical shell under aerody-namics and in-plane force is investigated by the method ofmultiple scales by Yang et al [33] Nonlinear subharmonicresonances of the current-conducting thin plate in elec-tromagnetic field are studied by Hu and Li [34] Li and Guo[35] studied the subharmonic resonance of both ends of acomposite laminated circular cylindrical shell in a subsonicair flow under radial harmonic excitation by using themethod of multiple scales Jomehzadeh et al [36] investi-gated the nonlinear subharmonic resonances of graphene-matrix composite to the harmonic -e primary sub-harmonic and superharmonic responses of a fractionalviscoelastic plate are studied by Permoon et al [37] and asimilar research has been conducted for cylindrical shells byAhmadi and Foroutan [38] Hosseini et al [39] investigatedthe nonlinear forced vibrations of a viscoelastic piezoelectriccantilever in the cases of primary resonance and non-resonance hard excitation including subharmonic andsuperharmonic Naprstek and Fischer [40] studied the superand subharmonic synchronization effects of the van der Polequation on harmonic excitation It is found in the litera-tures that most of the researches on subharmonic resonancesare focused on the conservative systems having a single-degree-of-freedom system

In this study the subharmonic resonance characteristicsof a two-degree-of-freedom laminated composite platesubjected to transverse harmonic excitations are investi-gated -e innovation of this paper lies in that the nonlinearvibration modeling of the thin plates with arbitraryboundary shapes and boundary conditions and the non-linear vibration of the plates under different boundaryconditions can be studied by assuming the correspondingmode function -e rectangular plate with simply supportedboundary condition studied in this study is only a specificcase when the boundary shape is determined and theboundary is acted on by no external force In the absence ofinternal resonance the low-order and high-order modes areuncoupled and so they are studied separately Based on thetheory of higher-order shear deformation plate and vonKarmanrsquos geometric relationship the nonlinear dynamicequations are established by using Hamiltonrsquos principle -eordinary differential equations for the vibration of therectangular plate were derived by two-order discretizationusing the Galerkin method-emultiscale method is appliedto obtain an approximate solution to the resonance problemBoth the amplitude-frequency response equation and the

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

10 Shock and Vibration

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

4 Results and Discussion

Figure 2 is the amplitude-frequency response curve ofthe two-order modes of the rectangular laminated plate fordifferent excitation amplitudes when 13 subharmonicresonance occurs -e vertical coordinate represents theamplitude of two-order modes and the abscissa is thedetuning parameter P1 and P2 are the amplitudes of ex-ternal excitation It can be seen from Figure 2 that there aretwo steady-state solutions for the two-order modes re-spectively at the same excitation frequency When the ex-citation amplitudes are the same the amplitudes of the two

steady-state solutions increase gradually with the increase inexcitation frequency When the excitation frequency is thesame the influence of the excitation amplitude on thesteady-state solutions with small vibration amplitude of thetwo-order modes is significant -e solution with smallamplitude of the first-order mode increases with the increasein the excitation amplitude Contrary to the first-ordermode the solution with small amplitude of the second-ordermode decreases with the increase in the excitation ampli-tude For the same excitation frequency the influence of theexcitation amplitude on steady-state solutions with the largeamplitude of the two-order modes is not obvious

Figure 3 shows the amplitude-frequency response curvesof the two-order modes of the rectangular laminated platefor different damping values when 13 subharmonic reso-nance occurs -e vertical coordinate is the vibration am-plitude of the two-order modes and the abscissa is thedetuning parameter μ is a physical quantity that charac-terizes the damping coefficient of laminated materialsObviously it can be seen from Figure 3 that the damping

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

affects the range of the steady-state solution (ie distributionregion of the curve) As the damping value increases therange within which the solution of the subharmonic vi-bration exists becomes smaller while the two modal am-plitudes are also affected by the damping coefficient Withthe change in damping the overall change trend of theamplitude-frequency response curve of the two-ordermodesof the laminated plates is consistent

Figure 4 shows ptthe force-amplitude response curves ofthe two-order modes of a rectangular laminated plate underdifferent external excitation frequencies when 13 subharmonicresonance occurs -e vertical coordinate represents the vi-bration amplitude of two-order modes and the abscissa is theexternal excitation amplitude It can be seen from Figure 4 that

there are also two nonzero steady-state solutions for the twomodes respectively Under the same external excitation fre-quency the steady-state solutions associated with small am-plitudes first decrease and then increase with the increase in theexcitation amplitude and the solutions with large amplitudedecrease monotonously as the excitation amplitude increasesFor the same external excitation amplitude as the excitationfrequency increases the vibration amplitudes of the two modesalso increase -e trend of the force-amplitude response curvesof the two-ordermodes of the laminated plate remains identicalBesides from the analysis of the frequency-resonance curves itcan be found that the results of this paper are consistent with thequalitative results given by Hu and Li [28] and Permoon et al[37]

Based on the average (25a) and (25b) the bifurcationdiagram for the first-order vibration is simulated numeri-cally by the RungendashKutta method -e amplitude of theexternal excitation is selected as the control parameter of thesystem and the influence of the amplitude of the externalexcitation on the nonlinear vibration characteristics of thesystem is studied -e initial conditions are x10 08x20 11 and the other parameters related to the laminatematerials are the same as those in the above amplitude-frequency equation (24) -e global bifurcation diagram ofthe subharmonic vibration of the rectangular laminatedplate is obtained as shown in Figure 5

In Figure 5 the abscissa is the amplitude of the ex-ternal excitation and the vertical coordinate is the ab-stract physical quantity that represents the transversedeflection of the rectangular plate It can be seen fromFigure 5 that for a small amplitude of the external ex-citation the vibration response of the first mode of the

subharmonic resonance of the laminated plate is period-2motion As the amplitude of external excitation increasesthe vibration response of the system changes from pe-riodic motion to chaotic motion With the continualincrease in the amplitude of the external excitation theresponse of the system changes from chaotic motion toquasiperiodic motion and subsequently to period-2motion Finally the vibration response of the systemchanges to haploid periodic motion In the brief intervalwhen the amplitude of external excitation changes thefirst-order mode undergoes all the forms of vibration ofthe nonlinear response It shows a variety of dynamiccharacteristics At the same time the phase and waveformdiagrams of different vibration states are also obtainedFigures 6ndash10 show the waveforms and phase diagrams ofthe subharmonic vibration responses of rectangularlaminated plates under different vibration stages inFigure 5

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Similarly the RungendashKutta algorithm is utilized for thenumerical simulation of the average equations (28) of thesecond-order response and the initial value is selected asx30 14 x40 175 By choosing the excitation amplitudeas the control parameter the global bifurcation diagram ofthe second mode is obtained in Figure 11

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation

Figure 11 is the global bifurcation diagram of thesecond mode of the subharmonic vibration of rectangularlaminated plates It can be seen from the figure that as theamplitude of the external excitation increases the

vibration response of the second mode also presentsdifferent vibration forms When the amplitude of externalexcitation is small the vibration response of the system ischaotic With the increase in the amplitude of externalexcitation the system changes from chaotic motion toperiod-3 motion and then from period-3 motion tochaotic motion again Figures 12ndash14 show the waveformand phase diagrams of the second-order modes of thesubharmonic vibration of laminated plates with differentexcitation amplitudes

5 Conclusions

In this work the subharmonic resonance of a rectangularlaminated plate under harmonic excitation is studied -e vi-bration equations of the system are established using vonKarmanrsquos nonlinear geometric relation and Hamiltonrsquos prin-ciple -e amplitude-frequency equations and the averageequations in rectangular coordinates are obtained by using themultiscale method -e amplitude-frequency equations andaverage equations are numerically simulated in order to obtainthe influence of system parameters on the nonlinear charac-teristics of vibration-e following conclusions can be obtained

(1) -e results show that there are many similar char-acteristics in the nonlinear response of the uncoupledtwo-order modes which are excited separately whensubharmonic resonance occurs Under the sameamplitude of external excitation the amplitudes of thetwo-order modes increase as the excitation frequencyincreases along with both the subharmonic domainsFor the same excitation frequency the steady-statesolutions corresponding to the large amplitudes arealmost independent of the external excitation -edifference is that the steady-state solution with smalleramplitude of the first-order mode increases with theincrease in the excitation amplitude while that of thesecond-order mode decreases with the increase in theexcitation amplitude

(2) From the bifurcation diagram it can be concluded thatthe systemmay experiencemany kinds of vibration stateswith the change in the amplitude of external excitationsuch as quasiperiodic periodic and chaotic motion -evibration of laminated plates can be controlled byadjusting the amplitude of the external excitation
