RISThe Effects of Residual Stress Distribution and Component Geometry on the Stress Intensity Factor of Surface Cracks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stress intensity factor estimated by the appropriate modeling of components is essential for the evaluation of crack growth behavior in stress corrosion cracking. For the appropriate modeling ...
Failure Mode and Failure Strengths for Wall Thinning Straight Pipes and Elbows Subjected to Seismic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is important to assess the failure strengths for pipes with wall thinning to maintain the integrity of the piping systems and to make codification of allowable wall thinning. Full-scale ...
Alignment Rule for Non-Aligned Flaws for Fitness-for-Service Evaluations Based on LEFM
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: If multiple discrete flaws are detected that are in close proximity to one another, alignment rules are used to determine whether the flaws should be treated as nonaligned or as coplanar. ...
The Effect of the Distance From the Center of a Weld to the Fixed End on the Residual Stress and Stress Intensity Factor of a Piping Weld
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fixed conditions of butt welds between straight pipe and the valves or pump in an actual piping system are different from those of straight pipes. However, the effect of the fixed condition ...
Prediction of Fully Plastic Collapse Stresses for Pipes With Two Circumferential Flaws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fully plastic collapse stress for a single circumferential flaw on a pipe is evaluated by the limit load criteria in accordance with the JSME Code S NA-1-2004 and the ASME Code Section XI. ...
