Abstract :
The development and validation of multi-axial creep damage constitutive equations for A369 FP91 steel at 625°C was presented. Three aspects of research work were reported: 1) the development of a new set of creep damage constitutive equations based on Xu´s formulation [1], 2) the validation on this newly developed and an existing KRH type of constitutive equations were validated under plane stress and plane strain conditions, and 3) discussion and conclusion.
