I am new to AUTODYN and have used a little bit of ANSYS workbench. I have been looking at implementing a visco-hyperelastic constitutive model in AUTODYN. However, I could not find any way to do this. None the user subroutines that ANSYS/AUTODYN allows us to incorporate does contain a feature of implementing a user-defined hyperelastic or visco-hyperelastic material model.

Our objective is to model the high strain rate response of polyurea using AUTODYN.

If someone can throw some light on this topic, it would be helpful for my research.
