【 摘 要 】

Low amplitude impact tests on pristine, aged and damaged PBX 9501 specimens were performed to determine the critical impact-velocity threshold for violent reactions as a function of initial state. Tests were performed with a 2 kg hemispherical spigot projectile launched from a powder driven gun at PBX 9501 in lightly confined Modified Steven targets. HE damage was achieved by a single impact ranging in velocity from 36.9 to 54.4 m/s. External blast gauge and ballistic pendulum data were used to achieved with photodiode velocity screen array and PVDF gauges. Strain gage data were used to evaluate the response of the explosive to impact and characterize subsequent reaction profiles. Polarized light microscopy, scanning electron microscopy, and second harmonic generation techniques were used to perform post-test characterization on remaining PBX 9501 specimens.
