Internal residual stress of an 18.2-mm-thick eight-pass butt-welded plate joint is evaluated using the inherent strain analysis. The residual stress distribution is obtained in detail along the thickness direction from measurements using multiple strain gauges. The residual stresses agree well with the results of thermal elastic plastic analysis, as well as with values obtained by direct measurement of the specimen surface, which is not used in inherent strain analysis. These results indicate that both inherent strain analysis and thermal elastic plastic analysis are effective in evaluating internal residual stress. Therefore, each analysis method should be selected after considering the object to be evaluated and the characteristics to be analyzed.
