Abstract
A multi-axial, unified sinh viscoplastic material model has been developed to model the behaviour of advanced materials subjected to high temperature cyclic loading. 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 multi-axial form in a material user subroutine and validated against uniaxial test data. The results validate the implementation for both isothermal and anisothermal uniaxial loading conditions for as-new P91 steel.
