Abstract
Over the past decades there have been numerous papers on the shock response of materials and more specifically towards metal
powder compaction and consolidation. In general, the shock process for powdered materials has utilized the traditional pressure-volume
shock relationships proportioned to the initial packing densities of the powders. However, this approach and its resulting
data are in controversy due to the lack of knowledge of its associated particle strain and strain temperature uncertainties.
This paper will describe the current understanding as well as the experimental technique used to obtain the shock response
for distended materials. The above parameters are described within a pressure-strain-temperature interdependence. It was found
that the experimentally measured strain heat was not only a function of initial packing density but also a function of powder
size and distribution.
