Laser peen forming (LPF) is a process that elongates the peened metal surface and bends the overall shape with a shockwave, which is formed by a pulsed laser beam shocking the metal surface, penetrates the metal and introduces a residual impress stress field in the surface and inside. The methods of LPF including multi-full peening and multi-selective peen forming single curved face and saddle-saddle-shaped hyperboloid are studied. Mathematical mode of LPF is established, LPF of the sheet metal of different form and size is numerically simulated with the ABAQUS software and the availability of the analytical peen way is proved. The results show that different kinds of deformations can be obtained with diverse ways of peening. The simulation can offer accurate peening schemes for experiments, improve the efficiency and help replace the traditional test-peening with LPF.
