Abstract: In this paper we present a finite element model in frequency domain
which computes the Lorentz force that drives an electromagnetic forming (EMF)
process. The only input data required are the electrical parameters of the
capacitor bank, the coil and the work piece. The main advantage of this
approach is that it provides an explicit relation between the parameters of the
EMF process and the frequency of the discharge, which is a key parameter in the
design of an optimum EMF system. The method is computationally efficient
because it only requires to solve time-harmonic Maxwell's equations for a few
frequencies and it can be very useful for coil design and for testing modeling
conditions on complex three-dimensional geometries.
