Abstract

The central issue determining initiation response of explosive crystals to shock or impact is the generation of the energy necessary to cause molecular dissociation. This controls the initial rate of release of chemical energy. Here, the energy dissipated in the crystals as they undergo plastic deformation due to shock or impact is taken to be the source of the energy required to achieve initiation. This determines initiation sensitivity to shock or impact. Several problems are discussed including initiation of detonation and the von Neumann pressure spike structure of a detonation wave.
