| Abstract: | In this paper,the large deformation elastoplastic theory and the software of ANSYS5.5 are used to carry out the numerical simulation research on the process of the hydrostatic extrusion for the tungsten alloys with different extrusion parameters.The varied laws of the extrusion pressure and stress strain with extrusion parameters in the sample are obtained.The results of the simulation are in good agreement with the experimental results. |
