The value and distributing form of the residual stress in laser peening forming (LPF) decide the final sheet contour and deformation shape. To accurately control the distributing of the residual stress and shape the sheet in desiration, it was significant to invest the distributing form among single peen, multiply peen in the same spot and different spots. The experiment of 2mm thick AL6061-T6 and LY12CZ sheet with thickness of 1.2mm was carried out with Nd:Glass high power pulsed laser. The residual stress of peened target was measured by the X-350A stress analytical facilities. The influence of process parameters, such as laser energy, sheet size, peenning path to the residual stress distributing was investigated deeply. The mathematical modeling of shock wave load based on laser peening was established, and a finite-element analysis method based on the ANSYS/LS-DYNA software is applied to simulate the sheet deformation process.
