Study on numerical simulation of multi-micro laser shock forming

In order to predict multi-micro laser shock forming, finite element model of multi-micro laser shock forming was built using ABAQUS software and simulation results were validated by experiment. On this basis, influence law of process parameters on micro laser shock forming was discussed. The results show that numerical simulation of multi-micro laser shock forming effectively shows three- dimensional deformation characteristics of laser impact area, and distribution of surface morphology under characteristic path is consistent with the experimental results. The influence law of sheet maximum deformation with laser energy, overlapping rate and diameter of laser spot conforms to experiment results. It confirms that numerical simulation can correctly predict the morphology of multi-micro laser shock forming, and provide good guidance for research on multi-micro laser shock forming. © 2015, Editorial Board of Journal of Infrared and Laser Engineering.
