Abstract
This paper proposes an improved contactless measurement method for vibration stress of piping systems, by which the measurement time is shorter and the measuring works are more simple. The proposed method includes two processes, in whic...

This study describes inelastic seismic design of piping systems considering the damping effect caused by elastic-plastic property of a pipe support which is called an elastic-plastic support. Though the elastic-plastic support is proposed as inela...
A software system to perform SCC crack propagation analyses for complex and realistically shaped structures consisting of dissimilar materials, such as weld metal, base metal, etc., under weld residual stresses is presented in this paper. The syst...
Residual stress caused by cold bending of an austenitic stainless steel pipe was measured by X-ray diffraction method. Diffracted X-ray may be skewed by textures on steel surface may result in low accurate stress value. By adopting the finding tha...
Residual stress distribution of cold-bent austenitic stainless steel pipe was measure with neutron diffraction method. The configuration of the pipe was 2B in diameter and Sch160 in thickness, and it was bent 90degrees by bent radius ratio of r/D=...
