In laser assisted additive manufacturing (AM) an accurate estimation of residual stresses
and distortion is necessary to achieve dimensional accuracy and prevent premature fatigue …

Laser forming is one of the most recent forming processes developed which uses a laser
beam to induce a deliberate thermal stress on a workpiece to form a sheet metal …

This study conducted tensile tests on SA508 Gr. 1a low alloy steel and SA312 TP316
stainless steel piping materials under various strain rates at room temperature (RT) and …

The seismic design review guide in Japan was revised in September 2006 to address the
occurrence of a large earthquake beyond the design basis. In addition, Japanese nuclear …

The paper studies the effects of the load reduction (discrepancy between designing and real
loadings), strength match of the welded piping joint (WPJ), welding width, crack size and …

The seismic regulatory guide was revised in September 2006 and the Niigata-ken Chuetsu-
oki earthquake, whose magnitude was beyond the design base seismic motion, occurred in …

This paper presents plastic limit loads and approximate J estimates for axial through-wall
cracked pipe bends under internal pressure and in-plane bending. These loads and …

In the leak-before-break (LBB) design of nuclear power plants, crack opening displacement
(COD) is an essential element for determining the length of the leakage size crack. Recent …

This paper presents an evaluation model for the restraint effect of pressure-induced bending
(PIB) on the opening of a circumferential through-wall crack (TWC) and a result of its …

The structural analyses described in the present report were performed in support of the
NASA Engineering and Safety Center (NESC) Critical Initial Flaw Size (CIFS) assessment …
