Low amplitude impact tests on pristine and damaged, baseline' and 'aged' PBX 9501 specimens were performed to determine the critical impact-velocity threshold for violent reactions. 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 evaluate reaction violence relative to a steady-state detonation. Strain gage data were used to evaluate the response of the explosive to impact and characterize subsequent reaction profiles. Test results show that the damaged threshold 1) is lower than the pristine threshold and 2) is invariant to PBX 9501 lot-to-lot and age variables.

It has proved useful in studies of the chemistry and physics of initiation and detonation. We have experimentally investigated some of the effects on its properties...
