Numerical simulation on process of hydrostatic extrusion for tungsten alloy through concave dies with equal-strain contour lines

The numerical simulation of the hydrostatic extrusion process for tungsten alloy through the concave dies with the equal-strain contour lines was carried out in this paper by the large deformation and elastoplastic finite theory and ANSYS software. Both the pressure in the process of extrusion and the stress-strain distribution in the sample were analyzed, which founds a basis to the engineering application.
