Abstract

Based on the grouping method and lifting and lowering method, the weld joints of TCS stainless steel such as butt joint and corner joint were experimentally examined to clarify their fatigue properties in axial loading. The probabilistic S-N curves were established from the viewpoint of the survival probability and confidence level, and the stress concentration factors were evaluated by using finite element model. As a result, corresponding to fatigue life of N=2×10 ⁶, the mean values of fatigue limit for corner joint and butt joint are evaluated to be 162.7MPa and 173.7MPa, respectively. The stress concentration factors for butt joint and corner joint are evaluated to be 1.55 and 2.22, respectively.
