The inadequacies, in describing the high temperature creep damage of two industrial alloys (Part I) with a model where the anisotropic damage variable D depends only on time have been pointed out. It is therefore proposed to introduce directly strain rate in the damage law. This rule is then integrated into a unified viscoplastic model, with internal variables, that has been developed elsewhere. Some numerical simulations obtained with the complete formulation are reported and, in general, yield acceptable results.
