MODERN NOTIONS OF THE EFFECT OF SUPERDEEP PENETRATION
S. M. Usherenko UDC 534.2 This paper considers a number of questions of mass transfer and energy redistribution in a nonstationary process - superdeep penetration (SDP) of a flux of microstrikers into metal obstacles. On the basis of the set of known results, under the assumption of a dynamic phase transition inhibited at the stage of loss of long links due to the severe deformation an approach to the understanding of this phenomenon is proposed and estimates of the energetics of the SDP process are made.
