Dispersion of metals under shock-wave loading by relativistic electron pulses and impactors accelerated by electric explosion

Abstract

Depending on the geometry and amplitude–time characteristics of external impact, there may be accumulation of shock-wave energy in the samples, which reduces the time during which the structural materials retain their functional properties. Dispersion from the free metal surface of samples without and with pre-applied perturbations in the form of pyramids is considered. Under certain amplitude–time characteristics of external impact, dispersion from the tips of the pyramids occurs. The quantitative characteristics of dynamic destructive processes at different amplitude–time characteristics of external impact are determined for the purpose of introducing them into two- and three-dimensional codes to predict the behavior of metals under extreme conditions.
