| Abstract: | The development of tooling for the sheet metal deep drawing process is a time-consuming and expensive process. Finite element (FE) modeling of this process had the potential to reduce the time and cost of tooling development. The theory of static implicit method in numerical simulation in sheet metal forming and simulation software were described. A finite-element model of four-node quadrangle element was developed based on this. Using this model, oil pan, washing-trough deep drawing processes and wrinkling were simulated. The validity, feasibility and high efficiency of this analysis technology were testified with the good simulation results. |
