β¦ Synopsis
The probability of the shock initiation of a number of explosives under various conditions to projectile impact has been assessed. An outline is given of the curvent theory of shock initiation and the experimental results obtained are discussed in the light of this theory. It is shown that the presence of an inert material reduces the shock sensitivity of an explosive by acting as a diluent, thereby reducing the number of sites at which reaction can begin.

The importance of determining the volume of activation in chemical kinetic studies of the shock initiation of explosives is emphasized. Volumes of activation and energies of activation are calculated, utilizing existing thermal ignition-time data for shocked nitromethane. Two important conclusions a
The effects of compressive waves propagating ahead of stronger shock waves in a granular explosive have been investigated experimentally. In particular, the propagation and growth of 5.0 GPa shocks preceded by either a 3.2 GPa shock or a 2.0 GPa ramp wave having a 0.6/as rise time were examined in t
