VIRTUAL LABORATORYA structure laboratory in computer

VIRTUAL LAB VS REAL LABVirtual LAB aim is presenting condition in real labs test with approximation in Finite Element Method or Numerical Method

Real Lab always dealing with material which cause a lot of money, time and failure without prediction.

Virtual Lab disadvantage

For un usual Test sometime the result is not precision, but only a predictionFor Test never done eq. not in ASTM code, need a verification in real labs

How To in Virtual Labs

Several Software can be use for virtual labs. A finite element with high precision such as Ansys, Abacus and Adina or using a simple finite Element Software such as Sap2000 or Atena Or Else

Result from both Labs

A Sample Test

We are Going to test a sample of cylinder as this in real labs

Our aim is taking a stress strain curve in sample.Sample 15 cm in diameters and 30 cm in heightfc’ = 20 Mpa or K225

Preparation in Sample

Checking a Pressure in Cylinder

So it Might Be aboutAP

Using a Simple FEMModel of Sample Looks Like This

Testing In Virtual Labs

Adding A Pressure After Analyze Stress Location can be check

Sample 2

We are Going to test this Beam below

Preparation in Sample

Using Atena, creating the sample

So the Sample look like this
