| Abstract: | Cross wedge rolling is a complicate 3-D elastoplastic forming process . A nonlinear finite el- ement modeling for the process of cross wedge rolling is presented with the aid of ANSYS/LS- DYNA3D. The deformation character and the distribution of stress and strain on section of workpiece during stretching stage have been obtained. On the hasis of the deformation character and the distribution of stress and strain,the shoulder and cavity on the end of work piece have been analyzed. |
