Abstract:
The presence of radial and axial mechanical perturbations in metallic conductors (cylinders and flat plates) arising under the action of a nanosecond discharge current are proved experimentally. The amplitude of the mechanical perturbations in solid-state conductors oscillates. The radial component of the mechanical perturbation should be considered as a reason for a magnetohydrodynamic instability with mode $m$ = 0 and, accordingly, for the formation of strata at the electrical explosion of the conductor. Data for the electrical explosion of the metallic cylindrical conductor and flat metal sheet (foil) are presented.
