Wave Structuring Viscosity in the Shock Compaction of Solid Matter

When subjected to projectile impact, or the load imparted by detonation of an energetic explosive, the effected regions of a solid material will undergo pressure-induced compression through the passage of a shock wave initiated by the impact or explosion. Extent of compression is dictated by both the nature of the material and the intensity of the impact or explosion. The time history of compression as the shock wave encompasses a region within the granular material is rapid. Transient local temperature and density extremes can occur. The time history of the energy imparted by the shock wave is central to assessment of physical and chemical transitions brought about by the event. This time history is dictated by a solid-state viscosity of the shock-wave effected material.
