Hello,

I want to ad term to the constitutive equation in Abaqus and I want to inverse loping over time.

I would be so thankful for your help.

Such things are possible only with Fortran user subroutines. You would have to write UMAT (or VUMAT for Abaqus/Explicit) subroutine. You can find more details in Abaqus documentation (User Subroutine Reference Guide).
