The material model accounts for rate-dependent effects related to high temperature creep and cyclic plasticity effects such as isotropic and kinematic hardening. The material model, which is capable of simulating both isothermal and anisothermal loading conditions, is implemented in a material user subroutine and validated against uniaxial test data. The results indicate that the multi-axial implementation performs well for both isothermal and anisothermal uniaxial loading conditions for as-new P91 steel.
