Impact ignition of new and aged solid explosives
- Lawrence Livermore National Laboratory, P.O. Box 808, L-282, Livermore, California 94551 (United States)
The critical impact velocities of 60.1 mm diameter steel projectiles required to produce ignition are measured for new and aged confined charges of the HMX-based solid explosives LX-10, LX-04, PBX-9404, and PBX-9501. External blast overpressure gauges are employed to determine the relative violence of the explosive reactions. The experiment is modeled in DYNA2D using recently developed material strength models, and thermal energy deposition thresholds for impact ignition are found. {copyright} {ital 1998 American Institute of Physics.}
