The Simulation of a Novel Laser Indirect Shock Forming with SPH

Abstract:

In order to study a novel laser indirect shock forming mechanism which applies laser-driven flyer to load the workpiece, this paper uses the SPH method to study the behavior of laser indirect shock forming and simulate the process of the workpiece forming. The SPH method solves the problem about the mesh tangling encountered in extreme deformation and this paper presents some ideal results and histories. Through comparing the experiment result with the simulating result, it is easy to find that the analysis with the SPH method can predict the final shape of workpiece properly. To some extent, this paper could provide some helpful messages for the study on the novel laser indirect shock forming.
