Hi,

My names Chris, I am a beginner to SolidWorks simulation, my apologies if I use any incorrect terminology or assumptions.

But can someone please help me with a current project I am working on.

I am currently trying to model a rubber block being compressed by 2 metal plates (from top and bottom). I have attained raw stress-strain curve data from physical experimentation to

represent the material's non-linear elastic behavior.

So as of now, these are the things I have done to the model:

1) Draw the physical rubber block

2) Added forces of 1N @ the top and bottom of the rubber block, with a time dependancy using "Variation with Time" to represent the 2 blocks compressing the rubber. (force will be multiplied by the supplied time curve Y value)

3) Changed the Study time properties to match real life experimentation time

4) specified material properties with "Nonlinear Elastic", Poisson ratio 0.4995, Thermal Expansion 0.0002/K, Mass Density 358 kg/m^3, Tensile Strength 13789514 N/m^2

The only thing left which I do not quiet understand is the constraints I need to place on the mode, Can someone please help me with this ?

And please let me know if I left anything important out.

Thanks for your help
