The Shock Compaction of Brittle Granular Materials: Particle Size Effects

Several continuum models can represent the shock compaction of brittle granular materials. Their success is limited by their insensitivity to mesoscopic features. There is therefore a need to quantify the effects of these mesoscopic features on the material's bulk shock response. impact experiments have been conducted on mono and bi-disperse glass microspheres with differing particle size distributions. Hugoniot relationships and shock-wave profile features are discussed with regard to the differences in particle size.
