I am working on a small FEM project involving PEEK interfacing with UHMWPE using a software package from ADINA. We are testing this construct on an MTS machine at a displacement rate of 2mm/min in our testing lab. Does anyone have any stress/strain data (curves), either uniaxial, biaxial, triaxial and in compression for PEEK at a similar loading rate that I can use as input data for material parameters? Where can I find this same data for conventional (non-irradiated) UHWMPE?

Thanks,
Tim
