Abstract

In this paper we investigate the shock compression and also the unloading of shock-loaded metals, taking into account the air in the pore spaces between the grains of continuous metal. We study the range of pressures and temperatures of the air during the shock compression, wherein the contribution of the thermal radiation of the air to the pressure and energy is still unimportant. The experimental results, obtained in the pressure range 40–850 kbar for Ni, Cu, and W, agree within experimental error with calculated data. We give the experimental results for the unloading of porous copper from a pressure state of 485 kbar.
