Shock Wave

The Handbook of Shock Waves contains a comprehensive, structured coverage of research topics related to shock wave phenomena including shock waves in gases, liquids, solids, and space. Shock waves represent an extremely important physical phenomena which appears to be of special practical importance in three major fields: compressible flow (aerodynamics), materials science, and astrophysics. Shock waves comprise a phenomenon that occurs when pressure builds to force a reaction, i.e. sonic boom that occurs when a jet breaks the speed of sound.This Handbook contains experimental, theoretical, and numerical results which never before appeared under one cover; the first handbook of its kind.The Handbook of Shock Waves is intended for researchers and engineers active in shock wave related fields. Additionally, R&D establishments, applied science & research laboratories and scientific and engineering libraries both in universities and government institutions. As well as, undergraduate and graduate students in fluid mechanics, gas dynamics, and physics. Key Features* Ben-Dor is known as one of the founders of the field of shock waves* Covers a broad spectrum of shock wave research topics* Provides a comprehensive description of various shock wave related subjects* First handbook ever to include under one separate cover: experimental, theoretical, and numerical results

The phenomenon of shock wave reflection was first reported by the distinguished philosopher Ernst Mach in 1878. Its study was then abandoned for a period of about 60 years until its investigation was initiated in the early 1940s by Professor John von Neumann and Professor Bleakney. Under their supervision, 15 years of intensive research related to various aspects of the reflection of shock waves in pseudo-steady flows were carried out. It was during this period that the four basic shock wave reflection configurations were discovered. Then, for a period of about 10 years from the mid 1950s until the mid 1960s, investigation of the reflection phenomenon of shock waves was kept on a low flame all over the world (e. g. Australia, Japan, Canada, U. S. A. , U. S. S. R. , etc. ) until Professor Bazhenova from the U. S. S. R. , Professor Irvine Glass from Canada, and Professor Roy Henderson from Australia re initiated the study of this and related phenomena. Under their scientific supervision and leadership, numerous findings related to this phenomenon were reported. Probably the most productive research group in the mid 1970s was that led by Professor Irvine Glass in the Institute of Aerospace Studies of the University of Toronto. In 1978, exactly 100 years after Ernst Mach first reported his discovery of the reflection phenomenon, I published my Ph. D. thesis in which, for the first time, analytical transition criteria between the various shock wave reflection configurations were established.

Florida Department of Law Enforcement agent Bill Tasker is still smarting from a near-lethal run-in with the FBI. But he reluctantly helps the Bureau track down a stolen Stinger missile. As usual, the Feds take all the credit—but something about this whole setup doesn’t feel right. Tasker decides to poke around, and stirs up trouble with his boss, the FBI, the ATF, and, worst of all, a gentleman who loves to blow things up—the bigger, the better. The bomber hasn’t killed anyone yet, but if Tasker keeps snooping around—well, there’s a first time for everything…

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.

For this edition, a number of typographical errors and minor slip-ups have been corrected. In addition, following the persistent encouragement of Olga Oleinik, I have added a new chapter, Chapter 25, which I titled "Recent Results." This chapter is divided into four sections, and in these I have discussed what I consider to be some of the important developments which have come about since the writing of the first edition. Section I deals with reaction-diffusion equations, and in it are described both the work of C. Jones, on the stability of the travelling wave for the Fitz-Hugh-Nagumo equations, and symmetry-breaking bifurcations. Section II deals with some recent results in shock-wave theory. The main topics considered are L. Tartar's notion of compensated compactness, together with its application to pairs of conservation laws, and T.-P. Liu's work on the stability of viscous profiles for shock waves. In the next section, Conley's connection index and connection matrix are described; these general notions are useful in con structing travelling waves for systems of nonlinear equations. The final sec tion, Section IV, is devoted to the very recent results of C. Jones and R. Gardner, whereby they construct a general theory enabling them to locate the point spectrum of a wide class of linear operators which arise in stability problems for travelling waves. Their theory is general enough to be applica ble to many interesting reaction-diffusion systems.

In the United States, about 60 percent of men and 50 percent of women experience, witness, or are affected by a traumatic event in their lifetimes. Many of them (8 percent of men and 20 percent of women) may develop post-traumatic stress disorder (PTSD)--a life-altering anxiety disorder. Once connected mainly with veterans of war, PTSD is now being diagnosed in many situations that cause extreme trauma such as rape, physical attacks or abuse, accidents, terrorist incidents, or natural disasters. The millions of family members of those who have PTSD also suffer, not knowing how to help their loved one recover from the pain. Shock Waves is a practical, user-friendly guide for those who love someone suffering from this often debilitating anxiety disorder, whether that person is a survivor of war or of another harrowing situation or event. Through her own experience, extensive research, advice from mental health professionals, and interviews with those working through PTSD and their families, Cynthia Orange shows readers how to identify what PTSD symptoms look like in real life, respond to substance abuse and other co-occurring disorders, manage their reactions to a loved one's violence and rage, find effective professional help, and prevent their children from experiencing secondary trauma. Each section of Shock Waves includes questions and exercises to help readers incorporate the book's lessons into their daily lives and interactions with their traumatized loved ones.

An original middle-grade graphic novel from Graphix starring Brooklyn's Spider-Man, Miles Morales, by bestselling author Justin A. Reynolds and Eisner nominee Pablo Leon! Miles Morales is a normal kid who happens to juggle school at Brooklyn Visions Academy while swinging through the streets of Brooklyn as Spider-Man. After a disastrous earthquake strikes his mother's birthplace of Puerto Rico, Miles springs into action to help set up a fundraiser for the devastated island.

Reynolds (Opposite of Always) and Eisner award-nominated artist Pablo Leon (Refugees) create a riveting story that will connect with new and well-versed comics readers alike.

One of the main goals of investigations of shock-wave phenomena in condensed matter is to develop methods for predicting effects of explosions, high-velocity collisions, and other kinds of intense dynamic loading of materials and structures. Based on the results of international research conducted over the past 30 years, this book is addressed not only to experts in shock-wave physics, but also to interested representatives from adjacent fields of activity and to students who seek an introduction to the current issues.
