FATIGUE STRENGTH ANALYZING METHOD OF WELDED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a fatigue strength analyzing method of a welded structure capable of efficiently performing fatigue strength of an examining part such as a weld line by automatically processing detection of stress direction and selection of a fatigue strength chart in a computer without relying on manpower. ;SOLUTION: In a method for analyzing fatigue strength of a welded structure composed of plural members, a fatigue strength analyzing method of the welded structure evaluates fatigue strength by respectively comparing these stresses with fatigue strength charts by determining stress in the vertical direction and the parallel direction to a weld line from a stress analyzing result of this welded structure by respectively selecting a fatigue strength chart in the direction parallel to the weld line and a fatigue strength chart in the direction vertical to the weld line on respective parts on the basis of a shape and a welding method of welded two members.;COPYRIGHT: (C)2001,JPO
