| Abstract: | In this paper, elastic plastic large deformation finite element method based on static implicit scheme for the simulation of the forming process of sheet metal is introduced. According to the methods presented in the paper, software for the simulation of sheet metal forming process is developed. The results calculated by the software developed for hydrostatic bulging of rectangular sheet coincide with the typical test results. A rectangular sheet two dimensional stretching with a hemispherical punch is simulated and numerical results are given. |
