RISEstimation of Stress Corrosion Cracking Growth Behavior Under Weld Residual Stress in the Bottom of a Reactor Pressure Vessel by Finite Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for evaluating crack growth by repeatedly modeling and analyzing the transitional crack shapes is developed for a general computing environment in which a commercial finite element preprocessor and analysis code ...
Long Term Stability of Residual Stress Improvement by Water Jet Peening Considering Working Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To prevent primary water stress corrosion cracking (PWSCC), water jet peening (WJP) has been used on the welds of Nibased alloys in pressurized water reactors (PWRs). Before WJP, the welds are machined and buffed in order ...
