Available in PDF, EPUB and Kindle. Book excerpt: Important understanding has been gained about the process of shock induced exothermic reactions in solid explosives. The initial step in the process has been shown to involve a breaking of intra molecular bonds or an altering of the bonds of the explosive molecules which make up the lattice of the material and a production of trapped radicals. These trapped radicals are likely candidates for the secondary reactions. It is also shown that this bond breaking is accompanied by considerable permanent distortion in the lattice.

Download or read book Toward Detonation Theory written by Anatoly N. Dremin and published by Springer Science & Business Media. This book was released on 1999-06-04 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is known that the Chapman-Jouguet theory of detonation is based on the assumption of an instantaneous and complete transformation of explosives into detonation products in the wave front. Therefore, one should not expect from the theory any interpretations of the detonation limits, such as shock initiation of det onation and kinetic instability and propagation (failure diameter). The Zeldovich-Von Neuman-Doring (ZND) theory of detonation appeared, in fact, as a response to the need for a theory capable of interpreting such limits, and the ZND detonation theory gave qualitative interpretations to the detonation limits. These interpretations were based essentially on the theoretical notion that the mechanism of explosives transformation at detonation is a combustion of a layer of finite thickness of shock-compressed explosive behind the wave shock front with the velocity of the front. However, some experimental findings turned out to be inconsistent with the the ory. A very small change of homogeneous (liquid) explosives detonation velocity with explosive charge diameter near the rather sizable failure diameter is one of the findings. The elucidation of the nature of this finding has led to the discovery of a new phenomenon. This phenomenon has come to be known as the breakdown (BD) of the explosive self-ignition behind the front of shock waves under the effect of rarefaction waves.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a systematic summary of a series of achievements of blast injury studies in China and the latest progress in blast injury treatment including injuries caused by various explosion accidents (such as coal mine gas explosion, and chemical explosion) and terrorist bombing around the world over the past three decades. The book not only covers comprehensive introductions to the knowledge and injury theories about explosive shock waves, but also expounds the prevention and treatment of various explosion shock injuries and their complications with generalized summaries. This book not only contains a diverse range of content, but also immense practicality. It elaborates on the causes of various types of explosion and impact injuries, as well as protection and treatment measures, serving not only as an important basis and technical support for military health service support in modern warfare, but is also extremely important in providing practical value in peacetime disaster prevention, mitigation and relief for patients.

Available in PDF, EPUB and Kindle. Book excerpt: Chemistry at Extreme Conditions covers those chemical processes that occur in the pressure regime of 0.5–200 GPa and temperature range of 500–5000 K and includes such varied phenomena as comet collisions, synthesis of super-hard materials, detonation and combustion of energetic materials, and organic conversions in the interior of planets. The book provides an insight into this active and exciting field of research. Written by top researchers in the field, the book covers state of the art experimental advances in high-pressure technology, from shock physics to laser-heating techniques to study the nature of the chemical bond in transient processes. The chapters have been conventionally organised into four broad themes of applications: biological and bioinorganic systems; Experimental works on the transformations in small molecular systems; Theoretical methods and computational modeling of shock-compressed materials; and experimental and computational approaches in energetic materials research. * Extremely practical book containing up-to-date research in high-pressure science * Includes chapters on recent advances in computer modelling* Review articles can be used as reference guide

This book was released on 2022-04-01 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Modeling of the Sensitivities of Energetic Materials, Volume 22 introduces experimental aspects, explores the relationships between sensitivity, molecular structure and crystal structure, discusses insights from numerical simulations, and highlights applications of these approaches to the design of new materials. Providing practical guidelines for implementing predictive models and their application to the search for new compounds, this book is an authoritative guide to an exciting field of research that warrants a computer-aided approach for the investigation and design of safe and powerful explosives or propellants. Much recent effort has been put into modeling sensitivities, with most work focusing on impact sensitivity and leading to a lot of experimental data in this area. Models must therefore be developed to allow evaluation of significant properties from the structure of constitutive molecules. Highlights a range of approaches for computational simulation and the importance of combining them to accurately understand or estimate different parameters Provides an overview of experimental findings and knowledge in a quick and accessible format Presents guidelines to implement sensitivity models using open-source python-related software, thus supporting easy implementation of flexible models and allowing fast assessment of hypotheses
