These include among others, impact, friction, heat, spark, and intense from the fundamental importance of studying laser interaction with energetic materials, laser initiation has many advantages when compared to conventional by: Abstract.
In the study of the initiation of solid, polycrystalline explosives by short-duration (thin) shock waves, several investigators have found that the relationship between initial pressure (P) and shock duration (tau) can be described with the equation P/sup 2/ tau = const.
Different mechanisms have been proposed to explain this relationship. commercial explosives ranges from to g/cc. For free running explosives, the density is often specified as the pounds of explosives per foot of charge length in a given size borehole.
With few exceptions, denser explosives give higher detonation velocities and pressures. Density is an important consideration when choosing an explosive. A model of mechanical initiation of solid explosives, applicable for analysis of sensitivity of individual substances and composite explosives, is developed.
The model includes a system of equations of work softening of a high explosive charge under an impact, resulting dissipative heating, and heat release due to chemical reactions between the Cited by: 2.
The mechanism of shock initiation to detonation in heterogeneous explosives is best described as local decomposition at hot spots that are formed by shock interactions with density discontinuities. The liberated energy strengthens the shock so that as it interacts with additional inhomogeneities, hotter more» hot spots are formed, and more of.
Revised and expanded to reflect new developments in the field, this book outlines the basic principles required to understand the chemical processes of explosives. The Chemistry of Explosives provides an overview of the history of explosives, taking the reader to future developments.

Abstract. The shock initiation of detonation in a solid explosive with gas inclusions is studied numerically by way of a two-fluid model.
The fluid-dynamic equations of a reactive medium are solved in a two-dimensional Lagrangian frame of : H. Qin, D. Spalding.

THEORY OF INITIATION OF DETONATION IN SOLID AND LIQUID EXPLOSIVES G. ADAMS The experimentally observed differences in the growth of shock initiated detonation in liquid and in solid explosives are discussed with the object of deciding upon a reaction rate model for numerical calculations on the growth of reactive shock waves in granular solid by: 1.
Experimental results often show that a prompt shock response to projectile impact can be experienced by even relatively heavily cased explosives. This paper will discuss the predictive criteria that can be applied in such circumstances, and in particular will explore the different mechanisms which are present for rod and sphere impacts.
Chemical kinetic thermal decomposition models of pressed solid high explosives containing octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) and triaminotrinitrobenzene (TATB), which accurately calculate the times to explosion at various initial temperatures measured in the one-dimensional time to explosion (ODTX) test, are extended to higher temperatures to predict the critical.
Chapter EXPLOSIVES DEFINITIONS 1. An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
Pyrotechnic substances are included even when they do not evolve Size: KB. The study presented here was conducted to investigate if the common Dutch method of making training aids (impregnating stainless steel tubes or other objects with the odor of an explosive by storing them for a minimum of 24 hours in a glass jar with solid explosives but without direct contact with the explosives) could be used to train the dogs to reliably detect different kinds of solid TATP.
In this work, we have focused on the initiation sensitivity of a solid explosive and performed numerical analysis of sympathetic detonation.
The numerical analysis is calculated by LS-DYNA 3D (commercial code). To understand the initiation reaction of an explosive, Lee-Tarver equation was used and impact detonation process was analyzed by ALE by: 1. •The world’s largest supplier of commercial explosives • 28% market share – 50 countries • 4 mil.
