| Abstract: | The constitution equations of Lagrangian and Eulerian configuration under a large deformation condition are studied. The finite element algorithms are also given respectively. The calculating results by the Eulerian algorithms are in good accordance with the experiment, showing that the Eulerian configuration is more resonable for the metal finite deformation problem. |
