PROBLEM TO BE SOLVED: To provide a method for easily and rapidly evaluating the fatigue characteristic of a T-joint in a T-type welded joint structure without performing a complicated fatigue test.;SOLUTION: In this method, the fatigue characteristic of the T-type welded joint structure is evaluated using a welding toe strain evaluation parameter expressed by formula (1): welding toe strain evaluation parameter=(1.13×10-2×ρ-0.59)×(1.05×10-4×UEHAZ+1.64×10-2)×(5.15×YPHAZ-0.92). Here, ρ(mm) is welding toe curvature radius of the T-joint, UEHAZ is uniform elongation (%) of a welding heat-affected zone of the T-joint, and YPHAZ is yield stress (MPa) of the welding heat-affected zone of the T-joint.;COPYRIGHT: (C)2012,JPO&INPIT
