Paper Abstract

The electromagnetic forming is a process to manufacture a part from sheet metal. The final shape of the part depends on the geometry of the dies, the material behaviour of the workpiece and the process parameters. This paper describes magnetic field transient analysis into electromagnetic forming devices using the finite element method (FEM). The electromagnetic force which causes plastic deformation of a metal disk is obtained from flat coil covered by a damped sinusoidal current. One finite element model, with nonlinear structural and electromagnetic material properties, is solved in two dimensions. Magnetic induction for a nonlinear axisymmetric electromagnetic forming device is shown to agree closely with measurements.
