Abstract
EARLIER work1,2 has shown that the initiation of liquid and solid explosives by impact or friction is due to the formation of localized hot spots. These hot spots may be generated by adiabatic compression of small entrapped bubbles, by friction and shear at solid surfaces, and, in extreme cases, by the viscous heating of rapidly flowing explosive. It was found that for nitroglycerine the minimum temperature of the momentary hot spot necessary for initiation by friction Was c. 400–500° C.
