Salient Features of Inertial Stretching of a High‐Gradient Conducting Rod in a Longitudinal Low‐Frequency Magnetic Field

From the viewpoint of the model of a uniformly stretching cylindrical incompressible rigid‐plastic conducting rod, the salient features of deformation of metal cumulative jets in a longitudinal low‐frequency magnetic field are considered. The electromagnetic processes proceeding in the jet segments when they enter or leave the region with a magnetic field have been investigated. It is shown that the electromagnetic forces arising as the result of deformation of the jet with the magnetic field that has penetrated into its material should inhibit the development of plastic instability, extending the stretching stage of the jet before it breaks up into separate segments and thus creating prerequisites for increasing its penetrating power capacity. The magnetic‐field parameters that enable one to expect a noticeable manifestation of the stabilizing effect have been estimated.
