Shock Waves Explosions

Understanding the causes and effects of explosions is important to experts in a broad range of disciplines, including the military, industrial and environmental research, aeronautic engineering, and applied mathematics. Offering an introductory review of historic research, Shock Waves and Explosions brings analytic and computational methods

This unique and encyclopedic reference work describes the evolution of the physics of modern shock wave and detonation from the earlier and classical percussion. The history of this complex process is first reviewed in a general survey. Subsequently, the subject is treated in more detail and the book is richly illustrated in the form of a picture gallery. This book is ideal for everyone professionally interested in shock wave phenomena.

As an editor of the international scienti?c journal Shock Waves, I was asked whether I might document some of my experience and knowledge in the ?eld of blast waves. I began an outline for a book on the basis of a short course that I had been teaching for several years. I added to the outline, ?lling in details and including recent devel- ments, especially in the subjects of height of burst curves and nonideal explosives. At a recent meeting of the International Symposium on the Interaction of Shock Waves, I was asked to write the book I had said I was working on. As a senior advisor to a group working on computational ?uid dynamics, I found that I was repeating many useful rules and conservation laws as new people came into the group. The transfer of knowledge was hit and miss as questions arose during the normal work day. Although I had developed a short course on blast waves, it was not practical to teach the full course every time a new member was added to the group. This was suf?cient incentive for me to undertake the writing of this book. I cut my work schedule to part time for two years while writing the book. This allowed me to remain heavily involved in ongoing and leading edge work in hydrodynamics while documenting this somewhat historical perspective on blast waves.

Materials processing using explosion, shock-wave and high-strain-rate phenomena was developed after WWII, and these explosive forming and welding techniques have since been adopted as an accepted industrial technology. Such extremely high-rate phenomena historically used empirical experiences while the experimental conditions were not well documented due to the difficulties inherent in understanding the real response or behaviour of materials. Based upon the recent development of numerical techniques for analysis and the enriched data available on the behaviour of materials, it is now possible to predict such high-rate phenomena based upon numerical and experimental approaches including optical observation. Explosion, Shock-wave and High-strain-rate Phenomena of Advanced Materials demonstrates the deformation of various materials at high-rate based upon numerical analysis and supported by experimental evidence. The book is recommended for researchers and engineers who would like to learn more about the high-rate effect of materials and those who need to resolve multi-physics problems based on numerical approach. It is also ideal for researchers and engineers interested with explosive and other high-rate processing of materials. Presents numerical techniques on the analysis and enriched data on the behavior of materials based upon a numerical approach Provides case studies to illustrate the various methods discussed Includes mechanical response at high-rates of porous materials

This book compiles a variety of experimental data on blast waves. The book begins with an introductory chapter and proceeds to the topic of blast wave phenomenology, with a discussion on Rankine-Hugoniot equations and the Friedlander equation, used to describe the pressure-time history of a blast wave. Additional topics include arrival time measurement, the initiation of detonation by exploding wires, a discussion of TNT equivalency, and small scale experiments. Gaseous and high explosive detonations are covered as well. The topics and experiments covered were chosen based on the comparison of used scale sizes, from small to large. Each characteristic parameter of blast waves is analyzed and expressed versus scaled distance in terms of energy and mass. Finally, the appendix compiles a number of polynomial laws that will prove indispensable for engineers and researchers.
