In the 1950s explosives began to be used to generate ultrahigh pressures in condensed substances in order to modify their properties and structure. Notwithstanding the short duration of an explosion, its energy proved to be high enough to perform physical-chemical transformations of substances, and the new method gained wide industrial applications. It has both advan tages and drawbacks in comparison with the traditional method of static compression. The latter method, notorious for its cumbersome and expensive machin ery, allows one to maintain high pressure as long as one pleases and to regu late the temperature of the sample arbitrarily. But, the pressure available is rather limited and for any increase of this limit one has to pay by the progres sive shrinking of the working volume of a press. The dynamic method has the advantages of low cost and practically no restrictions of magnitude of pressure and the size of a processed sample, but the temperature in a compressed body is no longer controlled by an experi mentor. Rather, it is firmly dictated by the level of loading, according to the equation of state. Hence, it is difficult to recover metastable products and impossible to prepare solids with a low concentration of defects as the dura tion of explosion is too short for their elimination.

Damaging accidental explosions are a continuous threat to industry. Categories for such explosions include combustible dust explosions; reactive gas explosions, both confined and unconfined; hybrid explosions involving both gases and dusts; bursts of pressure vessels and piping; and liquid propellant explosions. This book evaluates the physical processes and resulting blast effects for these types of explosions. Special attention is given to reactive gas explosions, both confined and unconfined. This latter class of explosion has occurred all too frequently in refineries and petrochemical complexes, and is also one of the most difficult to predict and evaluate. Much recent work on this topic is reviewed and summarized. This is the only publication of its kind, to date, that offers such a thorough coverage of these types of industrial explosions. [p] Each class of explosion source is reviewed separately, first discussing fundamentals, then presenting methods of analysis and testing, and finally giving curves or equations to predict effects of the particular class of explosion. An extensive bibliography is included together with tables of pertinent properties of explosive materials. The text also includes many figures, equations, tables and a keyword index. The book is intended for researchers in the field of characterizing and mitigating industrial explosions. It will also be of interest to engineers, scientists, and insurers involved in processes.

Hazardous Material Transportation Risks in the Puget Sound Region

The effects of an explosion of a methanol tank car were estimated using the model in PNL-2133 (Rhoads 1978). Consequence estimates from these models were adjusted to account for the larger amount of material.

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. With that goal in mind, the book opens with a brief account of the theoretical background and a short description of experimental techniques. The authors then progress to a systematic treatment of special topics, some of which have not been fully addressed in the literature to date.

This book highlights how the properties and structure of materials are affected by dynamic high pressures generated by explosions, projectile impacts, laser compression, electric discharge or ball milling. Starting with the basics of shock-wave physics and an outline of experimental techniques, it then surveys dynamic compressibility and equations of state of various substances, phase transitions and syntheses of novel compounds under shock. It covers various industrial applications including hardening of metals and grinding (fragmentation) of solids, saturation of solids with defects for use as catalysts, production of superhard materials (synthetic diamond, BN (boron nitride)) and nanomaterials, especially nanodiamond, and discusses state-of-the-art techniques such as combining dynamic and static compression to obtain monolithic materials.

Written by a hazardous materials consultant with over 40 years of experience in emergency services, the five-volume Hazmatology: The Science of Hazardous Materials suggests a new approach dealing with the most common aspects of hazardous materials, containers, and the affected environment. It focuses on innovations in decontamination, monitoring instruments, and personal protective equipment in a scientific way, utilizing common sense, and takes a risk-benefit approach to hazardous material response. This set provides the reader with a hazardous materials "Tool Box" and a guide for learning which tools to use under what circumstances. Dealing with hazardous materials incidents cannot be accomplished effectively and safely without knowing the effects these materials have. Volume Three, Applied Chemistry and Physics, is not about teaching chemistry and physics. It is about presenting these topics at the level that emergency responders will understand so they can apply the concepts using a risk management system. FEATURES Uses a scientific approach utilizing analysis of previous incidents Offers a risk-benefit approach based upon science and history Provides understanding tools for your Hazmat Tool Box Simplifies physical and chemical characteristics Utilizes chemistry and physics to identify hazards to responders

Composite materials are increasingly used in many applications because they offer the engineer a range of advantages over traditional materials. They are often used in situations where a specified level of performance is required, but where the cost of testing the materials under the extremes of those specifications is very high. In order to solve this problem, engineers are turning to computer Modelling to evaluate the materials under the range of conditions they are likely to encounter. Many of these analyses are carried out in isolation, and yet the evaluation of a range of composites can be carried out using the same basic principles. In this new book the editor has brought together an international panel of authors, each of whom is working on the analysis and Modelling of composite materials. The overage of the book is deliberately wide; to illustrate that similar principles and methods can be used to model and evaluate a wide range of materials. It is also hoped that, by bringing together this range of topics, the insight gained in the study of one composite can be recognized and utilized in the study of others. Professional engineers involved in the specification and testing of composite material structures will find this book an invaluable resource in the course of their work. It will also be of interest to those industrial and academic engineers involved in the design, development, manufacture and applications of composite materials.
