Critical review the development of creep damage constitutive equations for high Cr steels
نویسندگان
چکیده
The creep deformation and failure of high Cr steel component and weld is a challenging problem for power generation industries. There is a lack of good understanding of the precise nature and role of cavitation on the creep deformation and rupture. Creep damage constitutive equation developed either specifically developed for this type of steel or borrowed from existing one have been used in research. This review demonstrates the current state of art and outlines the direction of future work.

This paper presents a review of creep deformation and rupture mechanisms of low Cr-Mo alloy for the development of its creep damage constitutive equations under lower stress. The most popular Kachanov-Robatnov-Hayhurst (KRH) formulation was not necessarily developed and calibrated for low stress and cannot depict the creep strain accurately under multi-axial state of stress due to the three-dim...
