✦ Synopsis

Extension of earlier worh on the transition ]rom burning to detonution o[ cast explosives

shows that the inertia of the confining tube plays a major part in such transition.

Tube rupture with pentolite occurs only after a pressure equal to or greater than the shoch initiation pressure has been reached in the ignition area, and a]ter detonation has started about 10 cm beyond this area. Interruption of the pentolite column with a plug o] che~nically inert material permits transmission o[ compressive disturbances but blochs any transport processes. .4 subsonic ]font, originating near the region where the confined burning occurs, proceeds through the explosive at a constant velocity which is unaffected by passage through the inert plug. The low velocity disturbance is initiated in pentolite by a pressure o] a few hilobars, and it is suggested that this front is an ignition phenomenon.
