摘　　要：运用ABAQUS建立激光喷丸有限元模型,模拟研究不同材料的板材在激光冲击后折弯角度的变化,并进行相关实验,将仿真结果与实验结果进行对比。结果表明:金属材料HEL跟材料凹凸变形转换范围有关。We used ABAQUS to build the finite element model of laser peening to simulate the change of the bending angle of different materials after the laser peening, and then carried on the related experiments. Simulation results and experiment resultsd were comapred. Finally, we got the conclusion that the metal material＇ s HEL is related to the transformation range of the concave and convex deformation of the material.
