MODELING THE DEEP DRAWING OF AN AISI 304 STAINLESS-STEEL RECTANGULAR CUP USING THE FINITE-ELEMENT METHOD AND AN EXPERIMENTAL VALIDATION

Abstract

In this paper the deep drawing of a rectangular cup from AISI 304 stainless steel sheet was investigated numerically and experimentally. The finite-element method was used for computer modeling of the deep-drawing process. The thickness distribution predicted from the finite-element analysis was compared with experimental measurements. It was observed that the numerical results agree well with the experimental values. The minimum thickness was observed at the punch radius in both the simulation and experiment.
