The effect of residual stress on the SCC using ANSYS

Abstract

SCC (Stress Corrosion Crack) is a key issue in the nuclear industry of piping section. When weldingthe pipe, heat input occurs to the trend of thermal stress. And heat input affected residual stress to the pipe.In this study, the effect of residual stress for the SCC in the piping was determined.Experimental method is four kinds of specimens(1 pass, 5 pass, 10pass, 15pass) are produced toSCC. ANSYS codeanalyze the temperature gradient forthe specimen. Using the temperature gradient analyzedtothe residual stress in the pipe. According to this result, ascertain the effect of residual stress to SCC
