| Abstract: | In this paper, the transformation of stress-strain field in the process of laser bending is simulated with FEM, The rule of elastic-plastic deformation of top and bottom of sheet-metal in the bending process is also analyzed. The relationship between the technique parameters and the deformation is investigated, The simulation results are in good agreement with the experiment results. |
