SIMPLIFIED IDENTIFICATION METHOD FOR ESTIMATING RESIDUAL STRESS DISTRIBUTION DUE TO WELDING BY BOUNDARY ELEMENT METHOD

The residual stress due to butt welds may affect the reliability of a welded structure because brittle fracture, buckling fracture, and fatigue life may be affected. The measurement of welding residual stress in carried out by destructive or non-destructive methods, but these methods require much time and labour. A simplified identification method based on the boundary element method is proposed to estimate the residual stress distribution due to butt welding of thin plates. The validity of the proposed method was confirmed by numerical experiments when random measurement errors are included in the measured value.
