Abstract

This paper summarizes and presents research progress on the fundamentals of the development of creep damage constitutive equations for high Cr steels including 1) a brief summary of the characteristics of creep deformation and creep damage evolution and their dependence on the stress level and the importance of cavitation for the final fracture; 2) a critical review of the state of art of creep damage equation for high Cr steels; 3) some discussion and comments on the various approaches; 4) consideration and suggestion for future work. It emphasizes the need for better understanding the nucleation, cavity growth and coalesces and the theory for coupling method between creep cavity damage and brittle fracture and generalization.
