Abstract
A simplified identification method using a thermoelastic boundary element method is proposed to estimate residual stress distribution due to weld. The proposed method can simply estimate residual stress distribution by few measurement data, which are measured by nondestructive (or destructive) method This paper examine the effects of the location of measurement point and measurement errors. The validity of the proposed method is demonstrated by numerical simulation by thermoelastic boundary element. The applicability and the effectiveness of the proposed method was confirmed by using measuring data with random measurement errors at two kinds of location of the measurement points..
