    visco-plastic strain rate dependence material umat

    Dear all, I'm working on a material model with strain rate dependence, I found a very useful subroutine in the literature, that I modified for my purpose, and it is actually relatively working fine (it depend of the elastic modulus), it doesn't use the effective Jacobian, for high values of...
