| Abstract: | An analysis of edge rolling with 3D model is developed with the Rigid Plastic FEM. The slab shapes and the rolling force calculated by FEM are in good agreement with the experimental ones for materials Al in ambient temperature and 2S Al in various temperatures, and better precision is obtained. A new method in which an array of extreme thin elements is used to cope with singular point is presented, calculation program is simplified and a good result is rapidly reached. |

| Keywords: | D rigid plastic FEM steady state slab edging extreme thin element |
