Crystal orientation effects in PETN explosive with 4 GPa shocks

摘要: Shock initiation of detonation has been observed in PETN crystals /l angle/110/r angle/ orientation at the low shock strength 4.25 GPa. This result explains some observations by other workers Los Alamos National Laboratory that were considered anomalous. Chemiluminescent emission from shock-induced decomposition reactions using OMA spectrographs, photodiodes, and image intensifier cameras. The is not seen insensitive orientations, angle/100/r angle/101/r angle/; these orientations can deform primary slip plane, (110). 4 refs.
