Experimental and numerical analysys of multistage deep drawing

Résumé

The paper presents an analysis of the multistage deep drawing process considering the two deformation schemes namely direct and reverse redrawing. The analysis is based on numerical simulation using the finite element method, a powerful tool for analyzing complex three dimensional sheet metal forming problems. The results of numerical simulation are experimental validated. Finally it is concluded the importance of the material load pattern in the redrawing process toward the parts quality and forces level.
