We have recently conducted a series of tests in which unconfined explosive disks mounted onto a polycarbonate plate are impacted at low velocities (15-40 m/s) by a rounded projectile. We used high speed videography to record the impact event from the back side of the plate. We observe the damage evolution prior to ignition, and monitor the velocities where ignition occurs in different explosive formulations. We use these observations to inform the development and calibration of the High Explosive Response to Mechanical Stimuli (HERMES) explosive safety model [1]. In this work we assess the effects of various material parameters in the HERMES model on the observed mechanical behavior, which includes dynamic fracture and comminution. We calibrate our ignition model for comparison with low-velocity impact ignitions in other, more confined geometries such as the Steven test. [ABSTRACT FROM AUTHOR] |
