I am new to plastics. I have to simulate an impact test on thermoset plastic specimen using ANSYS. I am unable to figure out what kind of material model to be used. As we use rate-independent plasticity models in metal plasticity mostly Mises-plasticity are there any model to simulate rate-independent plasticity in thermosets. Or should I look for rate-dependent plasticity and things like that then what are choices in ANSYS. I went through the help but could not figure out any specific models for polyemers. Any tips will be highly appreciated.
