Numerical Simulation of Sheet Deforming Caused by Laser Shocking
Laser shock forming (LSF) is a new technique realized by applying a compressive shock wave generated by laser shocking on the surface of sheet metal. It is a mechanical, not a thermal process. After briefly reviewing the mechanism of LSF, instead of previously reported experimental research, a numerical simulation method of sheet deforming caused by laser shock waves is presented. The process of laser-shock plastic deforming of sheet metal is simulated with ABAQUS software, the simulation results are compared and agree well with the experiments on the condition of single laser shocking. It is shown that numerical simulation is available for optimizing laser parameters and predicting the sheet deformation contour of laser shock forming process.
