Flaws are the principal source of fracture in many materials, whether brittle or ductile, whether nearly homogeneous or composite. They are introduced during either fabrication or surface preparation or during exposure to aggressive environments (e. g. oxidation, shocks). The critical flaws act as stress concentrators and initiate cracks that propagate instantaneously to failure in the absence of crack arrest phenomena as encountered in brittle materials. This book explores those brittle materials susceptible to crack arrest and the flaws which initiate crack induced damage. A detailed description of microstructural features covering numerous brittle materials, including ceramics, glass, concrete, metals, polymers and ceramic fibers to help you develop your knowledge of material fracture. Brittle Failure and Damage of Brittle Materials and Composites outlines the technological progress in this field and the need for reliable systems with high performances to help you advance the development of new structural materials, creating advantages of low density, high resistance to elevated temperatures and aggressive environments, and good mechanical properties. - The effects of flaw populations on fracture strength - The main statistical-probabilistic approaches to brittle fracture - The use of these methods for predictions of failure and effects induced by flaw populations - The application of these methods to component design - The methods of estimation of statistical parameters that define flaw strength distributions - The extension of these approaches to damage and failure of continuous fiber reinforced ceramic matrix composites

This book presents the theoretical concepts of stress and strain, as well as the strengthening and fracture mechanisms of engineering materials in an accessible level for non-expert readers, but without losing scientific rigor. This volume fills the gap between the specialized books on mechanical behavior, physical metallurgy and material science and engineering books on strength of materials, structural design and materials failure. Therefore it is intended for college students and practicing engineers that are learning for the first time the mechanical behavior and failure of engineering materials or wish to deepen their understanding on these topics. The book includes specific topics seldom covered in other books, such as: how to determine a state of stress, the relation between stress definition and mechanical design, or the theory behind the methods included in industrial standards to assess defects or to determine fatigue life. The emphasis is put into the link between scientific knowledge and practical applications, including solved problems of the main topics, such as stress and strain calculation. Mohr's Circle, yield criteria, fracture mechanics, fatigue and creep life prediction. The volume covers both the original findings in the field of mechanical behavior of engineering materials, and the most recent and widely accepted theories and techniques applied to this topic. At the beginning of some selected topics that by the author's judgement are transcendental for this field of study, the prime references are given, as well as a brief biographical semblance of those who were the pioneers or original contributors. Finally, the intention of this book is to be a textbook for undergraduate and graduate courses on Mechanical Behavior, Mechanical Metallurgy and Materials Science, as well as a consulting and/or training material for practicing engineers in industry that deal with mechanical design, materials selection, material processing, structural integrity assessment, and for researchers that incursion for the first time in the topics covered in this book.

Structural steel has been vital to engineering and construction over the past century. Its versatility has allowed it to perform outstandingly in countless applications. However, there have been repeated failures associated with fracture and/or fatigue mechanisms; the 1994 Northridge earthquake, the 1995 Kobe earthquake, and most recently the I-35W Mississippi River Bridge collapse in Minneapolis on August 1, 2007. These failures have highlighted concerns for the life of bridge structures particularly with regard to fatigue and corrosion. Although problems with fatigue and brittle have been well documented, these factors and issues have not yielded state-of-the-art design practices. The goal of Reducing Brittle and Fatigue Failures in Steel Structures is to provide a one-volume reference of failures in steel structures, along with considerations to preventing them. This book will give engineers a better understanding of steel and its limitations and applications, in order to reduce brittle and fatigue failures. This book will be a valuable resource for structural engineers, as well as professionals involved in bridge construction, design, and maintenance.

The subject of mechanical behavior has been in the front line of basic studies in engineering curricula for many years. This textbook was written for engineering students with the aim of presenting, in a relatively simple manner, the basic concepts of mechanical behavior in solid materials. A second aim of the book is to guide students in their laboratory experiments by helping them to understand their observations in parallel with the lectures of their various courses; therefore the first chapter of the book is devoted to mechanical testing. Another aim of the book is to provide practicing engineers with basic help to bridge the gap of time that has passed from their graduation up to their actual involvement in engineering work. The book also serves as the basis for more advanced studies and seminars when pursuing courses on a graduate level. The content of this textbook and the topics discussed correspond to courses that are usually taught in universities and colleges all over the world, but with a different and more modern approach. It is however unique by the inclusion of an extensive chapter on mechanical behavior in the micron and submicron/nanometer range. Mechanical deformation phenomena are explained and often related to the presence of dislocations in structures. Many practical illustrations are provided representing various observations encountered in actual structures of particularly technical significance. A comprehensive list of references at the end of each chapter is included to provide a broad basis for further studying the subject.

Introduction to the Physical Metallurgy of Welding deals primarily with the welding of steels, which reflects the larger volume of literature on this material; however, many of the principles discussed can also be applied to other alloys. The book is divided into four chapters, in which the middle two deal with the microstructure and properties of the welded joint, such as the weld metal and the heat-affected zone. The first chapter is designed to provide a wider introduction to the many process variables of fusion welding, particularly those that may influence microstructure and properties, while the final chapter is concerned with cracking and fracture in welds. A comprehensive case study of the Alexander Kielland North Sea accommodation platform disaster is also discussed at the end. The text is written for undergraduate or postgraduate courses in departments of metallurgy, materials science, or engineering materials. The book will also serve as a useful revision text for engineers concerned with welding problems in industry.
