For a brief period during the latter part of World War II, Nevill F. Mott led a theoretical group at Fort Halstead in the United Kingdom that tackled scientific issues related to pressing war-time concerns. Among later awards and honors, Mott was knighted and a recipient of the Nobel Prize. While at Fort Halstead, he undertook an effort to theoretically describe the statistical fragmentation of munitions subjected to intense explosive loading. Mott`s original internal reports contain seminal theoretical concepts on the physics and statistics of dynamic fracture and fragmentation, which have provided the inspiration for numerous later modeling efforts and engineering formulae. Some of his most forward-looking thoughts on the micromechanical and molecular aspects of fracture are included in these publications. The present book surveys the theoretical analysis put forth by Mott with particular focus on his efforts to characterize the size and distribution of fragments resulting from a dynamic fragmentation event. Copies of the original internal reports of Mott and his co-workers are included. The book also pursues additional theoretical analysis with the intent of delving further into the physical ideas and unfinished analysis implicit in Mott`s original studies. This book will be of interest to all scientists and engineers concerned with the dynamic fracture and fragmentation of solid bodies subject to intense transient loads imparted by explosive detonation and high-velocity impact from both the historical and modern perspective.

Social Orders and Social Landscapes marks a new direction in research for Eurasian archaeology that focuses on how people lived in their local environment and interacted with their near and distant neighbours, rather than on overarching comparisons of archaeological culture complexes. Stemming from the 2005 University of Chicago Eurasian Archaeology Conference, the papers collected here reflect this new research agenda, though the way in which each author addressed the theme of the conference, and thus the book, was strikingly varied. This diversity arises out of the field’s intellectual flux driven by the principled engagement of the rich analytical traditions of the Soviet/CIS, Anglo-American, and European schools. Despite the variability in approaches and subject matter, several key themes emerged: 1) the reinterpretation culture categories by examining particular aspects of social life; 2) the role social memory plays in the production of landscape and place; 3) the influence of the built environment on societies; and 4) the ways in which economic considerations affect social orders and landscapes. The result is a book that helps to re-image Eurasia as a complex landscape fragmented by historically contingent and shifting ecological and social boundaries rather than a bounded mosaic of culture areas or environmental zones. “Scholarly research on Eurasia was transformed by the collapse of the Soviet Union in 1991. Entire areas and fields of research became accessible to European and American scholars for the first time, resulting in the emergence of new centers specializing in primary field investigations throughout the vast, politically transformed landmass of Eurasia. One such center is the University of Chicago that has recently sponsored two large international conferences on Eurasian archaeology. Social Orders and Social Landscapes is the product of the second Chicago conference held in spring 2005. The editors of the volume should be proud of their efforts that have resulted in such a broad ranging and prompt publication. The articles encompass a variety of disciplinary perspectives, including archaeology, history, art history, palynology, and zooarchaeology; extend chronologically from Neolithic and Bronze Age times to the formation of national identity in Turkey in the early 20th century; and range geographically from Europe to China. Several articles reconstruct basic subsistence activities; others analyze distinctive settlement types and political and cultural frontiers, including the assimilation and emergence of new, self-defined ethnic groups and the selective adoption of new systems of religious belief. What unites this diverse collection is their consistent emphasis on the social construction of reality and the production of social landscapes and memories that altered perceptions of the physical world and mediated the practical activities that here have been convincingly reconstructed from the archaeological record. In so doing, rigid stereotypes are questioned and novel interpretations persuasively advanced. Early Bronze Age pastoralism on the south Russian steppes did not consist exclusively of herding animals nor was it combined, as it was later in the Iron Age, with the pursuit of agriculture; rather, D. Anthony and D. Brown suggest that at least in the Samara river valley the herding of animals occurred along side the intensive gathering of wild, nutritionally rich plants. The kalas of ancient Chorasmia are not cities, nor even proto-urban formations, but rather are large, heavily fortified enclosures meant to repel attacks of armed nomadic cavalry. They represent a continuation of a distinct Central Asian settlement pattern that began in the Bronze Age and that formed the center of a landscape divided into contiguous, self-contained oases. The Mongols not only herded livestock, but also farmed, fished, hunted, and traded throughout the vast area that they had conquered, uniting most of Eurasia into a single, economically integrated system. New perspectives proliferate throughout this richly detailed and extremely broad ranging collected volume.” — Phil Kohl, Professor of Anthropology and the Kathryn W. Davis Professor of Slavic Studies at Wellesley College “ “Social Orders and Social Landscapes” is a stimulating addition to the still small literature in English making the rich datasets from the archaeology of Eurasia widely accessible to Western scholars. The authors of the eighteen chapters analyze data from China to the Mediterranean, from the fourth millennium BCE through the fourteenth century CE, with the tools of art and architectural history, text analysis, paleobotany and paleozoology, and anthropological theory, among others. The product of a conference at the University of Chicago, this book fulfils the goal of the graduate student organizers to apply interdisciplinary approaches to understanding the archaeology and history of the Eurasian landmass in local terms through a focus on “how people lived in their local environments.” In the decade and a half since the end of the Soviet Union, scholarly communication has broadened and the mutual influences have stimulated many new and thought provoking views on the Eurasian past. This book is an exemplary product of the new scholarly discourse.” — Karen S. Rubinson, Research Scholar, Department of Anthropology, Barnard College, Columbia University

The 16th European Conference of Fracture (ECF16) was held in Greece, July, 2006. It focused on all aspects of structural integrity with the objective of improving the safety and performance of engineering structures, components, systems and their associated materials. Emphasis was given to the failure of nanostructured materials and nanostructures including micro- and nano-electromechanical systems (MEMS and NEMS).

This reference explores explosion welding, a high intensity, transient impact that achieves metal compounds not obtainable otherwise. Electron microscopy images cover the structure of numerous welded joints including titanium–orthorhombic titanium aluminide, copper–tantalum, aluminum–tantalum, iron–silver, steel–steel, and copper–titanium. These weldable pairs have different solubility than their initial elements. The authors present various processes and structures including granulating fragmentation, cusps, splashes, and quasi-wave interface. Specific risk zones for chemical and petrochemical (coke chamber) reactors are probed and suggestions offered. Key Features: Offers new theories about explosion welding processes and structures Investigates dozens of weldable pairs with differing solubility from initial elements Studies both hetero- and homogeneous pairs Explores welded joints with flat, wavy and quasi-wavy separation boundaries Observes irregularities of the separation surface relief observing asperities and splashes and their transformation under intensified welding modes Unveils a new type of fragmentation under explosion welding Explosive Welding: Processes and Structures is a valuable resource for a wide range of experts involved in explosion welding, engineers, as well as graduate and postgraduate students.

This book is the second volume of Solids Volumes in theShockWaveScience and Technology Reference Library. These volumes are primarily concerned with high-pressure shock waves in solid media, including detonation and hi- velocity impact and penetration events. This volume contains four articles. The ?rst two describe the reactive behavior of condensed-phase explosives, and the remaining two discuss the inert, mechanical response of solid materials. The articles are each se- contained, and can be read independently of each other. They o?er a timely reference, for beginners as well as professional scientists and engineers, cov- ing the foundations and the latest progress, and include burgeoning devel- ment as well as challenging unsolved problems. The ?rst chapter, by S. She?eld and R. Engelke, discusses the shock initiation and detonation phenomena of solids explosives. The article is an outgrowth of two previous review articles: “Explosives” in vol. 6 of En- clopedia of Applied Physics (VCH, 1993) and “Initiation and Propagation of Detonation in Condensed-Phase High Explosives” in High-Pressure Shock Compression of Solids III (Springer, 1998). This article is not only an - dated review, but also o?ers a concise heuristic introduction to shock waves and condensed-phase detonation. The authors emphasize the point that d- onation is not an uncontrollable, chaotic event, but that it is an orderly event that is governed by and is describable in terms of the conservation of mass, momentum, energy and certain material-speci?c properties of the explosive.
