Three-dimensional modeling of explosive desensitization by preshocking by

Abstract The reactive three-dimensional hydrodynamic Code 3DE has been used to investigate the reactive hydrodynamics of desensitization of heterogeneous explosives by shocks too weak to initiate propagating detonation in the geometries studied. The preshock desensitizes the heterogeneous explosive by closing the voids and making it more homogeneous. A higher pressure second shock has a lower temperature in the multiple shocked explosive than in single shocked explosive. The multiple shock temperature may be low enough to cause a detonation wave to fail to propagate through the preshocked explosive.
