Using test data in hyperelastic model to get the parameters

[ohagan]

Hi, I am wondering if it is possible to obtain the elastic paramters from a model when using test data to define the paramters in the first place? For example say I have some stress-strain data, I use this with the polynominal model for N=2, and I want to know what ABAQUS then decides to use for the actual parameters of c10,c01,c11,c02,c20. Thanks.

by the way. I would like to obtain some material data (any kind of rubber) stress vs strain for free. Someone knows where i can obtain it ??
