Laser shock forming (LSF) is an advanced sheet forming technology which has extensive application prospects in micro electronics industry. A two-dimensional axial symmetric numerical model of SUS304 stainless steel is established. Finite element method is used to explore the dynamic deformation behaviors of the sheet driven by intense laser. The results show that the node velocity of metal sheet increases in an oscillatory manner in initial stage and then it starts to bulge. After collision with die cavity bottom, the central region of metal sheet jumps up reversely. Experiencing repeated damped vibration, the mental sheet gradually exhausts the obtained kinetic energy from the shock wave, and the metal sheet acquires the geometrical shape of die cavity. Increasing laser shock pressure can enhance the forming precision of metal sheet. The corresponding experiments are also carried out to verify the predicted results. The applied method and gained results can provide a reference for theoretical research and parameters optimization in LSF.
