文摘The new flexible forming technique of sheet metal laser bending process is numerically simulated by using finite element method of large elastic plastic deformation. The temperature fields and stress strain distribution in deformation area are calculated, forming process is described and relationship between bend angle and width of sheet is discussed. It is shown that the calculated values are in good accordance with the experiments.
