A Study on Multi-stage Deep Drawing Processes Using Finite Element Method

유한요소법을 이용한 다단계 디프 드로잉 공정에 관한 연구

There have been many researches performed on the formability of axisymmetric or rectangular cup shapes in the deep drawing processes. But non-axisymmetric deep drawing processes rely upon empirical knowledge of experts in most cases. Especially, there have been few researches for multi-stage elliptical deep drawing processes. In this study, formability and thickness distributions of elliptical yoke products were predicted by using finite element analysis. The results of the analysis were compared with those of experiments for validity.
