Abstract

A coupled finite element formulation is developed for the study of the stress wave in a conducting disk subject to transient magnetic field through a hole at the center of the disk. The formulation is derived directly from the coupled governing equations of electrodynamics of deformable solids of continuum mechanics. The electromagnetic and mechanical fields are nonlinearly coupled by the Lorentz body force effect in the mechanical subsystem and the mechanical velocity effect in the electromagnetic subsystem. Present formulation uses magnetic field vectors as primary variables for the electromagnetic subsystem that it eliminates the need of additional differentiation and keeps the consistency with the mechanical subsystem in the finite element method.
