In recent years, numerical simulation has been used to study the shock loading of powders and has begun to play an increasingly important role in understanding the phenomena as well as the underlying physical mechanisms. However, most numerical work has been carried out using continuum physics. For example, Flinn et al. [1,2] calculated the compaction of 304 stainless steel powders using an Eulerian hydrocode, CTH. Benson et al. used another hydrocode to investigate copper powders [3,4]. Both the works of Williamson et al. and Benson and Nellis have been seminal in elucidating such basic mechanisms as pore collapse, localized plastic flow, and temperature distribution during shock loading. The model of Benson is the first attempt to evaluate a realistic assembly of powder particles in terms of size and arrangement. A summary of his most recent work is found in Chap. 9 of this volume.
