Shock compression of solids as a physical-chemical-mechanical process
The changes introduced into solids while being processed through the abrupt stress and particle velocity transitions in the early portion of shock-compression pulses are not well described on a scientific basis, and their description presents perhaps the greatest challenge of modern shock-compression science. Over time scales from hundreds of picoseconds to hundreds of nanoseconds, solids are converted to states in which deformation is fluid-like to certain approximations. Descriptions of the transition regions have traditionally involved both physical and mechanical aspects. With recent studies of shock-induced solid state chemistry, the influence of chemical aspects must now be considered. Unfortunately, any change in chemical composition introduces substantial complications in analysis and interpretation of the shock-compression process. 40 refs., 3 figs.
