Finite Element Analysis of Angular Deep Drawing Process without Blank Holder

Abstract

The deep drawing method is widely used in the metal industry. With this method, metal sheets are formed in the desired form. In this study, a finite element analysis of the deep drawing process of DC02 sheet was made using an angular die. In the study, 15 different die radii were used. 10° die angle was used in all experiments. A blank holder was not used in this study. The effects of different die radii on the forming process were investigated. As a result of the study, it was determined that the most suitable die radius in terms of both equivalent plastic strains (PEEQ) and Mises stress was 8 mm. It was observed that the largest stresses occurred just above the cup radius, and the plastic strain increased as it moved towards mouth region of the cup.
