Book Description
The initiation of detonation by impact on an explosive is described and discussed in detail. The differences in behavior of homogeneous and heterogeneous explosives are delineated and discussed. A mathematical model is proposed which provides results agreeing with the results of an experimental study of the generation of detonation in a solid granular explosive. A critical examination of various theoretical studies of the initiation of detonation by shock wave is included.

Book Description
A brief study is given of experimental and analytical research on the detonation characteristics of low-density granular materials, which was carried out with a view toward acquiring greater understanding of (1) The mechanisms of initiation of detonation, (2) The mechanisms of propagation of detonation and (3) The characteristics of initiating shocks and of the transient and steady waves.

Book Description
The report is intended to provide Institute members with a concise discussion on the computation of the flow behind a shock leading to detonation in a one-dimensional system. The computation would be performed using the method of characteristics, and this reduction would also be used later for our investigation of the stochastic initiation of detonations. Stochastic effects might be introduced either as white noise or as variations in material properties such as so-called 'hot spots'. Mathematically these effects would appear as part of the 'driving terms' in the characteristic formulation. Consequently the purpose of the present report is to be viewed primarily as a supportive document for our research effort on the stochastic initiation of detonation.

Book Description
The Chapman-Jouget and ZND models of steady detonation have proved most useful for engineering estimation of the propagation of near-planar, steady detonation in short-reaction-zone explosives. However, even in well characterized systems, the purposeful initiation of detonation is not described by these models. The highly divergent and microscopic nature of point initiation require discerning experiments, modeling, and theoretical analysis. Recently, safety considerations in complex or damaged systems, possibly containing long-reaction-zone (insensitive) high explosives, have dominated the author's thinking. These situations are rarely planar or steady, the physical state of the explosive may not be easily characterized, and there is a wide range of potential stimuli. The high-explosive reaction may range from none, to deflagration, to partial detonation, or to full detonation. Techniques and data applicable to estimating the level of response are needed.

Book Description
This book describes the research of Bowden, Yoffe and their collaborators on explosive initiation. What Bowden and Yoffe showed was that explosives are ignited almost invariably by thermal processes and though other processes have been identified their work still holds.
