Numerical and experimental investigation on die and blank holder shape in deep drawing process

Abstract

In the present investigation, deep-drawing process of a cylindrical cup is simulated using non-linear implicit finite elements method to study the blank holder and die shapes. Punching and blank holder forces, drawing ratio, material flow and stress distribution are measured. Experimental and numerical results show that blank holder and die shapes influence punching and blank holder forces, drawing ratio, material flow. © 2008 Asian Network for Scientific Information.
