| Abstract: | In this paper, the key points encountered in simulating metal forming processes by rigid viscoplastic finite element method is studied. As a results, a general purpose FEN simulation system of forging processes is devloped in which some new algorithms are proposed. The metal flow of stigmata and the optimization design of die as examples are analyzed to show the validity and steabiliaty of this procedure. |
