Abstract

Experimental results on the response of solids to shock loading obtained by the original method capable of real-time recording of mesoscopic characteristics contradict the conventional representation of elastic-plastic transition within the local equilibrium concepts of continuum mechanics. Nonlocal mathematical modeling of spatiotemporal correlations in a shock pulse based on nonequilibrium statistical mechanics allowed uniting the obtained experimental data within the new physical representation of shock wave phenomena where the mesoscopic carriers of deformation were interacting wave packets. Microstructural investigations of the studied materials reveal different scales of deformation in three ranges of shock velocities, which are responsible for macroscopic properties of materials.
