For the sheet metal with large size and complex geometry shape such as autopanel, it is always a difficult and time consuming work to set up the FEM model of numerical simulation of stamping process. In the paper, the methods of modeling the FEM model of sheet with complex shape for stamping simulation were introduced. Based on the procedure of sheet metal forming numerical simulation, a new method directly creating FEM mesh from the scanned data was presented. The new method dramatically decreases the workload and enlarges the robustness of the modeling process. For dealing with the problem of the initial blank geometry is not clear, some predict methods were compared.
