metadata.value: Shock loading of M3 copper within strain rate range of 5·106
  -5,7·106 s
  -1 reveals a
  nucleation of structural objects of 5-30 µm in diameter, which present the three dimensional
  frameworks composed from shear bands of 50-200 nm spacing. The structures are shown to
  be nucleated by means of interference of longitudinal and periphery release waves. Transition
  of the material into structure unstable state responsible for the shear banding happens when
  rate of change of the velocity variance at the mesoscale becomes higher than the rate of
  change of the mean particle velocity. The sites of nucleation of 3D-structures are speculated
  to be the staking faults generated under action of chaotic velocity pulsations relevant to
  dynamic deformation. The physical model for formation of 3D-structures takes into account
  the intersection of the partial dislocations and Lomer - Cottrell barriers.
