Current State of Developing Creep Damage Constitutive Equation for 0.5Cr0.5Mo0.25V Ferritic Steel

This paper reports a critical summary of literature review of creep damage constitutive equations. Firstly, it introduces the general background on the creep damage in low alloy stainless steel and weldment. Then, it summarizes the typical creep damage constitutive equations for this material available from public literature and discusses the deficiencies existed in the popular creep damage constitutive equations. Finally it outlines the approach to be used in the developing a new set of creep damage constitutive equation and the directions of future work.
