Abstract
The influence of the skin effect on the fragmentation of wires due to pulsed currents was studied. It was found that the inclusion of the skin effect leads to a significant qualitative and quantitative effect on the elastodynamic state of a wire subject to a pulse current. It was observed that oscillations occur entirely under tension, while for a uniform current density stresses alternate between compression and tension on the longitudinal time scale. It was suggested that the skin effect increase the tensile τzz stresses responsible for wire fragmentation, with the magnitude of these increases being larger the shorter the current risetime.
