High-Pressure Multiple-Shock Response of Aluminum

  • R. J. Lawrence

It is well known that both dynamic yield strength and ratedependent material response exert direct influence on the development of surface and interface instabilities under conditions of strong shock loading. A detailed understanding of these phenomena is therefore an important aspect of the analysis of dynamic inertial confinement techniques which are being used in such applications as the generation of controlled thermonuclear fusion. In these types of applications the surfaces and interfaces under consideration can be subjected to cyclic loading characterized by shock pressures on the order of 100 GPa or more. It thus becomes important to understand how rate effects and material strength differ from the values observed in the low-pressure regime where they are usually measured, as well as how they are altered by the loading history.
