ACCOUNTING FOR FUNCTIONS OF DISTRIBUTION OF MECHANICAL PROPERTIES OF METALS IN DYNAMIC PROCESSES OF DEFORMATION AND DESTRUCTION OF BARRIERS

Based on a discrete model of a heterogeneous continuous medium, the possibility of constructing models of complex heterogeneous and gradient media has been shown. A generalization of the said model into construction metals having a spread of mechanical properties within a certain value range has been made. The performed calculations modeling the process of perforation of an aluminum barrier that has a normal yield stress distribution have shown a realistic conformity of the computational results to the experimental data
