Stress-Time Profiles, Hugoniot, and Shock Sensitivity Data for 1-GPa Shocks in Low-Density HMX (Octogen) Explosive

摘要

Using manganin gauges, plane-wave stress-time profiles were obtained for HMX explosive with 35% voids. Profiles were taken at several sample thicknesses for input stresses near 1 GPa. The objective was to observe the effect of the porosity on the compacting and initiating wave. The character of the initiation build-up is different from that seen in full-density explosives. Profiles in PBX 9404 were taken for comparison. These profiles should provide a good test for 1-D modeling of the compaction and initiation processes. Hugoniot and Pop-plot data for the pour-density HMX are also presented. 10 refs., 8 figs., 2 tabs. (ERA citation 11:041485)
