Abstract

Sheet metal forming is a widely applied industrial process that can be found in the fields of aerospace and automobile panel’s production, the conventional forming of sheet metal is realized by the Die and Mold, this method usually give rise to high cost, long production periods and little flexibility. In this paper, a flexible forming technique of sheet metal based on laser shock peening is presented and some preliminary experiments were carried out with Nd:Glass laser of a pulse of 20 nanoseconds long and 1.064μm wavelength, an energy per pulse of 10 to 30 joules. The mathematical modeling of sheet metal bulging based on laser shock peening was established, and a finite-element analysis method based on the ABAQUS software is applied to simulate the sheet bulging process. The numerical simulation indicates that the results agree well with the experiments under one laser shock peening. The investigation revealed that the combination of numerical simulation and experiments is a useful method to obtain the optimized laser parameters, and to better understand the sheet deformation characteristics under laser shock loading.
