rubber deformation simulate

If I were tasked with doing an analysis of something like this, the very first thing I'd do is search for similar topics people have brought up in the past. A simple Google of "creo simulate rubber" brings up a lot of past discussions which I'm not going to list here, but there are apparently some tricky parts to analysis of rubber, i.e. material properties, large deformations, and how to deal with contact due to deformation.
