Physical models are proposed which describe the rotational effect (formation of local rotated regions) in crystalline metallic materials at some regimes of schock-wave loading. The suggested models treat the rotational effect as being related to a crystal-to-glass-to-crystal transformation induced by an interaction of a shock-wave front with the local stress fields of dislocation pile-ups. In doing so, several variants of the evolution of defect structures in shockloaded metallic materials are examined which depend on shock-wave parameters. In particular, the formation of shear bands and microcracks both located within and near boundaries of the rotated regions are considered in detail. |
