Abstract

A high speed and the absence of a precise control over pressure distribution have confined the sheet EMF in a die to simple shapes having shallow depths. It is possible to reach a higher depth by applying a convex PUNCH instead of a concave die. In this work, sheet EMF on a PUNCH and sheet EMF in a die are investigated. The electromagnetic part of the work is analytically investigated, and its mechanical part is numerically studied using FEM in the Abaqus software. In order to couple the electromagnetic and mechanical parts, the no-coupling method is used. The results obtained are verified by comparing them with the earlier experimental ones in the literature. Al 1050 is used in this work. The rate-dependent and rate-independent hardenings are taken into consideration for the mechanical behavior of the material. Using an appropriate hardening model for the material yields acceptable results. Furthermore, a convex PUNCH is used instead of a concave die to reach a higher depth in sheet EMF.
