The Initiation of Explosion in Single Crystals by Collapsing Bubbles,
Abstract
The mechanism of initiation of explosion by the rapid compression of gas spaces has been studied using a high-speed framing camera capable of taking pictures at sub-microsecond framing intervals. Experimentally single crystals of explosive (silver azide, lead azide) were studied. Various processes were identified and measured during the bubble collapse including the speed of collapse, involution of the bubble to form a jet (velocity a few 100 m/s), and an expansion shock of strength about 1 kbar during the rebound stage. The importance of these various phenomena in the initiation of explosion was assessed by using different geometric configurations for the bubble collapse. (Author)
