How to convert a UMAT into VUMAT?

29 June 2017 1 5K Report

Dear Colleagues

I am using a UMAT for modeling the hysteresis behavior of a Material.

It is a simple UMAT which modify the elastic modulus of the material at different strains in order to reproduce the hysteresis behavior.

I need to convert it into a VUMAT for Explicit Dynamic simulation in ABAQUS.

What should I change in My code?

I have attached my code.
