What is the difference between strain hardening and modified strain hardening laws for creep?

      Modified strain hardening is the integral form of strain hardening assuming constant stress, so they are essentially the same for constant stress case, only difference is the calculation of creep strain, MSH will be more accurate regardless of time step. For none constant stress cases, they are just two models that fit to experiment, although they will likely closer to each other in the response. See attached pdf for more rigorous explanation.
