| Abstract: | The Theory and simulation techniques of 3 D rigid plastic finite element are systematically studied in this paper. In accordance with the key techniques such as describing curre surface of dies and handling on clynamic contacting bourdary in simulation, some effective methods of calculation are put forward,and a software for 3 D simulation is developed. Compression of square block with hemispheric punch and forming of crankshaft are simulated by this system, which indicates that the given methods and software are feasible. |
