A mathematical model was developed to predict the time displacement histories of objects translated by the blast winds from conventional or nuclear explosions; these predictions were then compared to actual experiments. The objects studied varied in size from 139 mg spheres to man and were all assumed to be free to move over a smooth horizontal surface. The effects of ground friction could either be included or neglected, but when they were considered the ground friction eventually brought the objects to rest after the winds had passed. The values of ground friction used were determined experimentally and were found to be functions of the velocity and mass of the object being displaced. The translational model was general enough for either classical or nonclassical blast waves to be considered. Results for a chemical explosion were obtained by using both the computed blast waves of various authors and the experimentally determined blast waves. These predicted results were compared with each other as well as with experimental data obtained with steel spheres. The model was used to determine dynamic pressure impulses necessary to explain the measured sphere velocities at three ranges from ground zero. Another mathematical model was briefly described which was developed to compute the detailed two-dimentional trajectories of objects as they roll, slide, and bounce along the ground. The model closely predicted the measured distances between bounces and the total displacements of concrete blocks and large stones and thus helped to explain the mechanisms of tumbling by which an irregular object may become airborne during both the accelerative and the decelerative phases of displacement.

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.

Explosion and Blast-Related Injuries is an authoritative text that brings together diverse knowledge gained from both the experience of clinicians treating blast casualties and the insights of scientists obtained from research and modeling of blast exposures. By providing information on explosion and blast injury patterns, as well as the mechanism of blast-induced injuries, it is a useful reference for both physicians and researchers. With contributions by experts from around the globe, the book covers topics such as the epidemiology of blast and explosion injury, pathology and pathophysiology, and the modeling and mechanism of injury. Finally, this book might stimulate additional studies into ways to improve our current mass casualty response systems. * Contains contributions from experts who had first hand experience dealing with explosion and blast injuries. * Provides a diverse global experience derived from both military operations and terrorist attacks in civilian settings from the US, Europe and the Middle East. * Covers such topics as epidemiology of blast and explosion injury, pathology and pathophysiology, modeling and mechanism of injury, and finally presents the global experiences of blast injury and mass casualty management.

The book introduces basic risk concepts and then goes on to discuss risk management and analysis processes and steps. The main emphasis is on methods that fulfill the requirements of one or several risk management steps. The focus is on risk analysis methods including statistical-empirical analyses, probabilistic and parametrized models, engineering approaches and simulative methods, e.g. for fragment and blast propagation or hazard density computation. Risk management is essential for improving all resilience management steps: preparation, prevention, protection, response and recovery. The methods investigate types of event and scenario, as well as frequency, exposure, avoidance, hazard propagation, damage and risks of events. Further methods are presented for context assessment, risk visualization, communication, comparison and assessment as well as selecting mitigation measures. The processes and methods are demonstrated using detailed results and overviews of security research projects, in particular in the applications domains transport, aviation, airport security, explosive threats and urban security and safety. Topics include: sufficient control of emerging and novel hazards and risks, occupational safety, identification of minimum (functional) safety requirements, engineering methods for countering malevolent or terrorist events, security research challenges, interdisciplinary approaches to risk control and management, risk-based change and improvement management, and support of rational decision-making. The book addresses advanced bachelor students, master and doctoral students as well as scientists, researchers and developers in academia, industry, small and medium enterprises working in the emerging field of security and safety engineering.

In this report the general phenomena connected with a blast wave in air will be discussed. The particular features of the blast wave produced by a nuclear explosion will be emphasized, but many of the developments in this volume will apply generally to blast waves produced by any type of explosion. In this introductory chapter we shall try to give a general idea of the various phenomena occurring in a blast wave in air, of their interrelation and their time sequence. In the following chapters the details of the theory will be given, including curves showing the pressure distribution as a function of time and position. We have not Included any detailed discussion of the effects of an atomic bomb other than the blast effect. Cnly a short discussion of other effects is given in Chapter 3. For further discussion, especially on flash burn and radioactivity, reports on the experience in Japan should be consulted.
