An experimental study of the dynamic response of porous two-thirds of crystal density copper, iron, and tungsten was performed, using manganin and quartz transducer techniques. The data acquired include measurements of Hugoniot and release states up to about 60 kbar for porous copper, 50 kbar for porous iron, and 140 kbar for porous tungsten. It was found that inclusions in the pores substantially altered the compaction behavior of porous copper and iron, but that above about 20 kbar, clean foams of these materials will compact to the volumes predicted by a Mie-Gruneisen equation of state. Tungsten foam exhibited substantial residual crushing strength up to at least 140 kbar, and was thus never fully compacted under the conditions of the experiments.
