What material model will be best for capturing the softening behavior of the Polyproylene. I know Multilinear kinematic hardening model does not take in negative slopes and therefore is not suitable. Is there even a way to go about it? I see Bergstorm-Boyce is one of the models that have been previously considered for polycarbonates. I do have the capability to all the required testing, I just need to understand the best material model choice and how to go about it.
