| Abstract: | CAE/CAD/CAM integralization is a trend in dies technology. An ana-lysis of the cold extrusion process by means of the rigid-plastic finite element method is found to be a useful approach in its CAE. In actual application, however, if the deformed body is of a kind of strain-hardening material, and the rigid zone accounts for the greater part of the deformed body to make the process an unsteady-state one, the convergence of iteration will be very bad. A new yield strength model of the material and the related equations of rigid-plastic finite element analysis have been proposed and used successfully in the cold extrusion of a truck tyre nut. |
