Abstract:
The development of detonation is examined in a low sensitivity explosive initiated by a diverging shock wave through an inert barrier. It is shown experimentally and by calculation that, in the case where the properties of the material and the geometric factors begin to have an effect, the initial zone within which an explosive material under conditions close to critical for detonation initiation begins to decompose lies in the periphery near the barrier and has an axially symmetric, annular shape.
