Any link to large strain viscoelastic modeling using user subroutines will be greatly appreciated.

This is first question in forum so please forgive for any mistakes.

We are trying to model hyperelastic and viscoelastic behaiour using user sub routine in autodyn to couple them later for a new model. We found that the present viscoelastic model is inadequate for modelling large strain. We are in need of any relevant material for carrying on further.

Thank you in advance.
