RISEffect of Weld Residual Stress Fitting on Stress Intensity Factor for Circumferential Surface Cracks in Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies have shown that the crack growth of primary water stress corrosion cracking (PWSCC) is mainly driven by the weld residual stress (WRS) within the dissimilar metal weld. The existing stress intensity factor ...
Residual Stress Characterization in a Dissimilar Metal Weld Nuclear Reactor Piping System Mock Up
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Timeofflight neutron diffraction, contour method, and surface hole drilling residual stress measurements were conducted at Los Alamos National Lab (LANL) on a lab sized plate specimen (P4) from phase 1 of the joint U.S. ...
