| Abstract: | The blank shape is an important factor in metal forming,a method to calculate the blank shape based on the results of FEM forming numerical simulation is developed in this paper.The method is a kind of geometric mapping,but the rule of material deforming is also taken into account,so it has a high degree of belief.On the other hand,the method can calculate blank shape with the result of Finite Element Analyzing (FEA) using self adaptive meshing. |

| Keywords: | algorithm blank shape self adaptive meshing Finite Element Analyzing |
