Abstract :
The present paper describes a numerical method to solve the problem of the electromagnetic forming of clamped thin circular metal sheets by using a flat spiral coil. The method involves circuit analysis, electromagnetic field calculation and the dynamic plastic deformation of the workpiece. A two-dimensional axisymmetric model based on the integral representation of the electromagnetic vector potential is proposed for the calculation of the magnetic field, eddy currents and the electromagnetic force density in the metal sheet. Equations for the motion of the loaded work-piece are used assuming plane stress condition
