Shock sensitivity of LX-04 at elevated temperatures
- Lawrence Livermore National Laboratory, P.O. Box 808, L-282, Livermore, California 94551 (United States)
Hazard scenarios can involve multiple stimuli, such as heating followed by fragment impact (shock). The shock response of LX-04 (85 weight {percent} HMX and 15 weight {percent} Viton binder) preheated to temperatures near 170C is studied in a 10.2 cm bore diameter gas gun using embedded manganin pressure gauges. The pressure histories at various depths in the LX-04 targets and the run distances to detonation at several input shock pressures are measured and compared to those obtained in ambient temperature LX-04. The hot LX-04 is significantly more shock sensitive than ambient LX-04. Ignition and Growth reactive flow models are developed for ambient and hot LX-04 to allow predictions of impact scenarios that can not be tested directly. {copyright} {ital 1998 American Institute of Physics.}
