Abstract

The paper reports on experiments and numerical simulation of high-speed impact loading of additively manufactured heterogeneous specimens. It is shown that the proposed model of direct numerical simulation of a heterogeneous material based on random distribution of given materials over difference cells accurately reproduces the processes of deformation, fracture, and cratering under impact loading. A series of calculations are made to determine the ballistic efficiency of additively manufactured heterogeneous metal-ceramic specimens using the DoP (depth-of-penetration) method. A procedure is proposed for estimating the efficiency of heterogeneous metal-ceramic specimens, revealing local maxima in it.
