| Abstract: | By applying the slitting method and Finite Element Method calculation,the measuring of welding residual stress and numerical analysis for the thin plate weldment of LY12 aluminum alloy were conducted.Excellent agreement between the measured value of longitudinal welding residual stress and FEM calculated value is presented.The research shows that the residual stress distribution from analysis supplied the theoretical basis for stress stature subjected in the course of the post-welding service for LY12 aluminum alloy thin plate.This study has practical significance. |
| Keywords: | slitting method welding residual stress stress measuring finite element method |
