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...
In welding, material is heating locally. Therefore, it generates tensile residual stress in the heat affected zone and changes the quality of material. Those will be causes problem of stress corrosion cracking in SUS304. One of the conventional pr...
The present paper proposes an efficient contactless measurement method for vibration stress of piping systems, by which the measuring works are performed for an extreme short time and the measured stress can be evaluated immediately after the meas...
