Abstract:

A high-speed photographic study was made of the initiation of explosive liquids using sparks and impact and of single crystals of explosive solids using shock and hot wires. The physical homogenuity of the material was shown to have a marked effect on its sensitivity. Studies of the fracture of inert solids showed the importance of specimen geometry, and of crack speed on the fragmentation process. Both high-speed photography and ultrasonic methods were used for the fracture work. One of the main advances was in the theoretical work on thermal explosion theory.
