Residual stress mapping in welds using the contour method.
In: 7th International Conference on Residual Stresses (ICRS-7) (Denis, S.; Hanabusa, T.; He, B. P.; Mittemeijer, E.; Nan, J.; Noyan, I. C.; Scholtes, B.; Tanaka, K. and Xu, K. W. eds.), 14-17 June, Xian, China, pp. 294–299.
The contour method, a newly-invented sectioning technique for residual stress measurement, has the potential to measure the cross-sectional residual stress profile of a weld in a simple and time-efficient manner. In this paper we demonstrate the capability of the contour method to measure cross-sectional residual stress profiles, which are compared with neutron diffraction measurements and show excellent agreement. The results provide useful information for safetycritical design of welded components and optimization of welding parameters, and also illustrate the potential of the contour technique as a powerful tool for residual stress evaluation.
