Hot Spot Initiation Patterns in Shocked Explosives and Propellants Recorded by Thermal Film.
Abstract
Recovery of thermally sensitive films from explosives subjected to low level, long duration shocks allows one to obtain in situ records of heating patterns and formation of hot spots. The degree of discoloration in the recovered film corresponds to reaction induced temperatures of the order of several hundred C. Differing patterns of initiation buildup may be observed in different explosive compositions. The film technique is also seen to be a more sensitive detector of low level reactions than the underwater bulk expansion optical method.
