Abstract
Materials structurization is the final step for manufacturing science and engineering, and welding is one of the essential technology for it. Welding residual stress generates when materials are structurized and residual stress causes fatigue, stress-corrosion cracking, reduction of structural strength, brittle fracture, buckling, and other failures in various components. A computational method as well as a direct measurement method is useful for evaluating weld residual stress and distortion. This paper introduces recently developed methods for innovative numerical simulations of the weld residual stress for materials structurization on various scales and in structures with various welds. Many applications of these analysis methods are expected in the near future.
