| Abstract: | Laser shock forming (LSF) of sheet metal is a new technique realized by applying an impulsive pressure generated by laser-induced shock wave on the surface of metal sheet.LSF of brass sheet metal was investigated using a Q-switched Nd:YAG laser with an energy per pulse of 15～50 joules.ABAQUS software was used to simulate laser shock forming process.The central displacement of the shocked region is measured and compared with the simulation.The higher pulse energy, the higher central displacement of the shocked region were obtained.The deformation of the simulation matches the experiment quite well. |
