The effect of RDX particle size on the shock sensitivity of cast PBX formulations: 2, Bimodal compositions

The effect of RDX particle size on the shock sensitivity and detonation velocity of two cast polyurethane-based bimodal RDX formulations has been determined. The shock sensitivity results (wedge test data) have been interpreted using a hydrodynamic code containing a three term ignition and growth model for build-up of detonation. 2 refs., 6 figs., 2 tabs.
