In order to identify the successive stages of developing the hierarchy of multiscale
mechanisms of dynamic straining, the shock-induced mesostructure formation is studied in
combined experiments. Shock tests of two kinds of aluminum alloy, 1561 and 1565 alloys
were conducted in parallel in two regimes of loading: (i) under uniaxial strain conditions and
(ii) in high velocity penetration. Combination of loading regimes allows the correlation in
formation of multiscale structure depending on strain rate and...
