Plenary Lecture 4
Modeling of Vibrations of Lumped and Continual Mechanical Systems by Ordinary Differential Equations
Professor Jan Awrejcewicz Technical University of Lodz
Department of Automation and Biomechanics Lodz, Poland
E-mail: awrejcew@p.lodz.pl Abstract: Example taken from mechanical engineering, i.e. dynamics of a triple physical pendulum exhibiting a plane motion (lumped system) and dynamics of a cylindrical shell with the circular cross section (continual system ) are studied. In the first case the Lagrange’a equations are used to derive the governing second order ODEs, whereas in the second case strongly nonlinear PDEs are reduced to a truncated set of ODEs via FDM (Finite Difference Method) and the higher order Bubnov-Galerkin approximations. Mathematical modeling of triple pendulum includes details, taking into account some characteristic features (for example, real characteristics of joints built by the use of roller bearings) as well as some imperfections (asymmetry of the forcing) of the real system. Parameters of the model are obtained by a combination of the estimation from experimental data and direct measurements of the system's geometric and physical parameters. A few versions of the model of resistance in the joints are tested in the identification process. Good agreement between both numerical simulation results and experimental measurements have been obtained and presented. Some novel features of our real system chaotic dynamics have been reported. In the case of the circular cylindrical shell dynamics the problems related to its regular, bifurcational and chaotic dynamics are illustrated and discussed, as well as it’s local (global) stability loss versus control parameters. In addition, the convergence and validity of the applied numerical algorithms are studied. The lecture includes movies and animations of regular and chaotic dynamics of the analysed systems. Brief Biography of the Speaker: Jan AWREJCEWICZ received the M.Sc. and Ph.D. degrees in the field of Mechanics from the Technical University of Lodz in 1977 and 1981, respectively. He received also his bachelor's degree in Philosophy in 1978 from the University of Lodz, and DSc. degree in Mechanics from the Technical University of Lodz in 1990.

Plenary Lecture 5
Design of Foundation Structures using the Mechanics of Unsaturated Soils
Professor Sai K. Vanapalli Co-author: Won T. Oh
Civil Engineering Department University of Ottawa, ON
Canada E-mail: Sai.Vanapalli@uottawa.ca
Abstract: Bearing capacity and settlement behavior are two key properties required in the design of foundations. In conventional geotechnical engineering practice, the bearing capacity of saturated soils are typically analyzed using two different approaches; effective and total stress approach using Terzaghi (1943) and Skempton (1948) bearing capacity theory, respectively. In most cases, the bearing capacity of unsaturated soils is also interpreted using the effective stress approach regardless of the type of soil (i.e., coarse- and fine-grained soils), which is not rational. In addition, the conventional theory for the estimation of immediate settlement using the modulus of elasticity, E of saturated soils cannot be extended for unsaturated soils or compacted soils as they do not attain saturated condition during their service period. The mechanics of saturated soils are however employed in practice due to the following two reasons: (i) extending the approach used for saturated soils to soils that are in a state of unsaturated condition provides conservative analysis and (ii) there is no simple framework to design geotechnical structures using the mechanics of unsaturated soils. In this paper, simple models are proposed for predicting both the bearing capacity and the modulus of elasticity of unsaturated soils for different types of soils. These models use the Soil-Water Characteristic Curve (i.e. SWCC), which is defined as the relationship between the water content and soil suction, as a tool along with saturated soil properties (i.e., bearing capacity and modulus of elasticity under saturated condition). Details of how the proposed models can be implemented into geotechnical engineering practice and differences associated with the proposed methods and conventional methods are also discussed with practical examples. Lastly, a method to estimate matric suction of as-compacted soils using a pocket penetrometer is described. The simple techniques proposed in this paper should encourage the geotechnical engineers to implement the mechanics of unsaturated soils in practice. Brief Biography of the Speaker: Dr. Vanapalli is a Professor and Graduate Program Coordinator of the Civil Engineering Department, University of Ottawa. Dr. Vanapalli received his PhD from the University of Saskatchewan in 1994. Since then, he has been actively involved with research activities related to mechanics of unsaturated soils including expansive soils. The focus of his research was primarily extended towards studying the mechanical behavior of unsaturated soils and proposing simple techniques for the estimation of the soil-water characteristic curve, bearing capacity and settlement behavior of unsaturated soils. Dr. Vanapalli has authored or co-authored over 120 research publications in peer reviewed journals and conference proceedings, a book chapter and three state-of-the-art reports. He has also delivered three Keynote addresses at the International Soil Mechanics Conferences on topics related to the mechanics of unsaturated soils. Dr. Vanapalli has been a Co-Chair for the Diamond Jubilee Canadian Geotechnical Conference held in Ottawa, Canada in 2007, Co-Chair of the 12 IACMAG, Goa, India in 2008 and advisor for the 14th Pan-American Conference on Soil Mechanics and Geotechnical Engineering Conference to be held in Toronto, Canada in 2011. He has served as Technical or Scientific Committee Member for several national and international conferences. He has reviewed publications for several technical journals that include Geotechnique, Canadian Geotechnical Journal, Journal of Geotechnical and Geo-environmental Engineering, American Society of Testing Materials, Soil Science Society of America and Transportation Research Board. Dr. Vanapalli has been nominated by the Civil Engineering Department and the Faculty of Engineering, University of Ottawa for the OCUFA Teaching Excellence Award (2007); University of Ottawa Award for Excellence in Teaching (2006); Civil Engineering Department for the John V. Marsh Teaching Excellence Award (2006). In addition, fifteen
