Evaluation of Fatigue Strength-Reduction Factor of Weldment under Elevated Temperature Considering Thickness Effect

概要

Analytical and experimental studies were conducted on the fatigue strength reduction factor (FSRF) of the weldments for breeder reactor structural design, focusing on the relationship between the strain constraint effect and the ratio of the welded metal breadth to the welded joint wall thickness. As the result, it was found that the FSRF for a 304SS-308 hot TIG welded joint is expected to be about 1. 1 for the wall thickness of the Japanese demonstration LMFBR vessel.
