Super-deep penetration phenomena as resonance excitation of self-keeping spall failure in impacted materials

The anomalous responses in solid loaded dynamically are linked with the generation of the spatial-temporal structures in defect ensembles. Scenario of the evolution of typical defects (microcracks, microshears) has the form of the nonequilibrium kinetic transitions. The generation of these structures is accompanied by the qualitative changes of solid responses to loading (left angle left angle dynamic branch right angle right angle under spalling, super deep penetration effect).
