Abstract

Drawbeads are applied in the deep drawing process to improve the control of the material flow during the forming operation. In simulations of the deep drawing process these drawbeads can be replaced by an equivalent drawbead model. In this paper the usage of an equivalent drawbead model in the finite element code DiekA is described. The input for this equivalent drawbead model is served by experiments or by a 2D plane strain drawbead simulation. Simulations and experiments of the deep drawing of a rectangular product are performed to test the equivalent drawbead model performance. The overall conclusion reads that a real drawbead geometry can succesfully be replaced by the equivalent drawbead model
