Abstract：

A thermo-mechanical coupled finite element model was developed to simulate the laser bending forming process of singly curved plate using the finite element software MSC.Marc. The temperature field, the stress field and the displacement field during the laser bending forming process were calculated and analyzed. Furthermore, the effects of the length of scanning line and the initial shape of singly curved plate on the laser bending forming were investigated. The results indicate that the bending deformation increases with the increase of length of scanning line, while decreases with the increase of curvature of singly curved plate. The reliability of finite element model was verified by the experimental results.
