HYDRODYNAMIC THEORY AND HIGH PRESSURE FLOW IN SOLIDS

Abstract

The range of validity of the application of the hydrodynamic theory to high pressure flow in aluminum, copper and salt (sodium chloride) is investigated. Data are being obtained for these materials when subjected to two-dimensional steady flow and when subjected to one-dimensional time-dependent flow. Two-dimensional flow is induced by covering one surface of the specimen with a slab of explosive which is detonated across one end. One-dimensional flow is induced by hitting the specimen with a thin, explosivedriven plate. In both cases, the motion of the free surface of the specimen is monitored to give the data necessary for calculating the peak pressure of the shock wave which caused the surface to move. The values of the peak pressures so determined are being compared with the results of calculations based on the theory of hydrodynamics. (Author)
