Over the course of the twentieth century, democracies demonstrated an uncanny ability to win wars when their survival was at stake. As this book makes clear, this success cannot be explained merely by superior military equipment or a particular geographical advantage. Instead, it is argued that the legal frameworks imbedded in democratic societies offered them a fundamental advantage over their more politically restricted rivals. For democracies fight wars aided by codes of behaviour shaped by their laws, customs and treaties that reflect the wider values of their society. This means that voters and the public can influence the decision to wage and sustain war. Thus, a precarious balance between government, parliament and military leadership is the backbone of any democracy at war, and the key to success or failure. Beginning with the sixteenth- and seventeenth-century writings of Alberico Gentili and Hugo Grotius, this book traces the rise of legal concepts of war between states. It argues that the ideas and theories set out by the likes of Gentili and Grotius were to provide the bedrock of western democratic thinking in wartime. The book then moves on to look in detail at the two World Wars of the twentieth century and how legal thinking adapted itself to the realities of industrial and total war. In particular it focuses upon the impact of differing political ideologies on the conduct of war, and how combatant nations were frequently forced to challenge core beliefs and values in order to win. Through a combination of history and legal philosophy, this book contributes to a better understanding of democratic government when it is most severely tested at war. The ideas and concepts addressed will resonate, both with those studying the past, and current events.

Shock wave research covers important inderdisciplinary areas which range from basic topics on gasdynamics, combustion and detonation, physico-chemistry of high temperature gases, plasma physics, astro and geophysics, materials science, astronautics and space technology to medical and industrial applications. This book includes 202 papers presented at the 18th the International Symposium on Shock Waves which describe the research frontier of shock wave phenopmena and 14 plenary lectures which show the state of the art of various fields of shock wave research. This proceedings is a unique collection of most important and updated shock wave research.

High Pressure Shock Compression of Solids IV

While much is known about the effects of shock compression on monolithic materials, the unusual physical and chemical processes that take place when a porous medium is shocked have hardly been studied until now. Here, leading researchers in condensed matter physics, physical chemistry, metallurgy, mechanics, and materials science bridge this gap. The focus is on heterogeneous deformation mechanisms, nonequilibrium thermodynamics, and chemical processes, covering such topics as modelling the complex interplay of thermal, mechanical, and chemical processes; experimental data on pore collapse and their interpretation; and synthesis of new materials through shock-induced chemical reactions. By presenting not only the most recent results, but also the open questions that remain, these essays convey the excitement of developing a scientific basis for understanding shock compression.

Both experimental and theoretical investigations make it clear that mesoscale materials, that is, materials at scales intermediate between atomic and bulk matter, do not always behave in ways predicted by conventional theories of shock compression. At these scales, shock waves interact with local material properties and microstructure to produce a hierarchy of dissipative structures such as inelastic deformation fields, randomly distributed lattice defects, and residual stresses. A macroscopically steady planar shock wave is neither plane nor steady at the mesoscale. The chapters in this book examine the assumptions underlying our understanding of shock phenomena and present new measurements, calculations, and theories that challenge these assumptions. They address such questions as: What are the experimental data on mesoscale effects of shocks, and what are the implications?; Can one formulate new mesoscale theories of shock dynamics?; How would new mesoscale theories affect our understanding of shock-induced phase transitions or fracture?; And what new computational models will be needed for investigating mesoscale shocks?

This book is aimed to make careful analysis to various mathematical problems derived from shock reflection by using the theory of partial differential equations. The occurrence, propagation and reflection of shock waves are important phenomena in fluid dynamics. Comparing the plenty of studies of physical experiments and numerical simulations on this subject, this book makes main efforts to develop the related theory of mathematical analysis, which is rather incomplete so far. The book first introduces some basic knowledge on the system of compressible flow and shock waves, then presents the concept of shock polar and its properties, particularly the properties of the shock polar for potential flow equation, which are first systematically presented and proved in this book. Mathematical analysis of regular reflection and Mach reflection in steady and unsteady flow are the most essential parts of this book. To give challenges in future research, some long-standing open problems are listed in the end. This book is attractive to researchers in the fields of partial differential equations, system of conservation laws, fluid dynamics, and shock theory.
