It is necessary to establish properly reliable weld residual stress analysis methods for accurate crack initiation and growth assessment of primary water stress corrosion cracking, which may occur in nickel-based dissimilar metal welds in pressuri...
Residual stress caused by welding processes affects characteristics of strength and fracture of equipment and piping in power plants. Numerical thermal elastic-plastic analysis is a powerful tool to evaluate weld residual stress in actual plants. ...
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...
