plastic nonlinear data

I have been doing some simulations with plastic parts and am wondering if there is a good resource somewhere to get nonlinear stress/strain curves for various materials. Matweb has a lot of material data, but I haven't seen any type of nonlinear information.

I am sure many others have done simulations with nonlinear materials... does a person always have to get their material tested in a lab?
