摘  要：
In this paper, the elastic plastic finite element method based on static implicit scheme for the simulation of the forming process of sheet metal was introduced. The numerical technique to simulate contact interface and the radial return method to calculate the stresses in the process of increment deformation were proposed. According to the methods presented in the paper, FEM code for the simulation of sheet metal forming process was developed. The results calculated by the code, which was developed for a rectangular sheet two dimensional stretching with a hemispherical punch, coincide with the typical calculated ones. The springback analytical results of sheet metal forming with cylindrical die were given in the paper.
