Dear all,
I would like to have creep with Drucker Prager plasticity.
When using the built-in creep, I faced the problem of
an equivalent creep stress which is dependent on the hydrostatic pressure.
My objective is to have an equivalent creep stress which is equal to the Von Mises equivalent stress.
I have been trying using the creep subroutine, but could not have a correct stress computation.
Could anyone help ?
regards,
