【Abstract】 The decoupling algorithm of the static implicit nonlinear equations and some key techniques for sheet metal forming simulation were described. The simulation results of benchmark C about the multi operation forming given by NUMISHEET 2002 were presented and compared with the experimental results. The application of the F.E. simulation techniques to the processes of sheet metal forming was discussed.更多还原
