| Abstract: | The metal elongation and compress process are simulated by using FEM(finite element method) of the 8 nodes isoparametric elastic plastic model.The information of strain field and the tension and compression force etc are gained.The single drum and the double drum in compressing processes and the necking in tension processes are gained.The calculating result are in good accordance with the experiment. |
