Dear everyon,
In my research, I need to create subroutine UMAT for Rousselier damage model.
I have already done it on VUMAT (for dynamics), and now I need to transfer my code to UMAT (for static problem).
The problem is that I haven’t known yet how to define the Jacobian (the consistent tangent modulus) for this theory.
Could anyone provide me the information about this term (the jacobian of Rousselier damage model)?
Thank you very much indeed
