摘要：
This paper presents the measurement of residual stress (RS) distribution at the weld root of a U-rib specimen using the contour method. A fully automated data processing code was developed to process the measured data over the cut surfaces. In addition, the effect of the applied boundary conditions (BCs) on the resulting energy and reproduced RS was examined using different BCs cases. Full 2D maps of RS distribution were obtained where a compressive RS was induced at the weld root. Moreover, it is found that the studied BCs cases have a small influence on the resulting energy and negligible effect on the general distribution of reproduced RS. © 2020 Japan Welding Society.
