Mechanical Behavior and Fracture of Engineering Materials


Book Description

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.




The Theory of Materials Failure


Book Description

A complete and comprehensive theory of failure is developed for homogeneous and isotropic materials. The full range of materials types are covered from very ductile metals to extremely brittle glasses and minerals. Two failure properties suffice to predict the general failure conditions under all states of stress. With this foundation to build upon, many other aspects of failure are also treated, such as extensions to anisotropic fiber composites, cumulative damage, creep and fatigue, and microscale and nanoscale approaches to failure.




Fracture at High Temperatures


Book Description




Fractography and Failure Analysis


Book Description

This book presents fractography and failure analysis at a level that is accessible for non-expert readers, without losing scientific rigor. It offers a comprehensive description of fracture surfaces in engineering materials, with an emphasis on metals, and of the methodology for the observation of fracture surfaces. It also discusses in detail the main fracture mechanisms and their corresponding fracture surfaces, including brittle, ductile, fatigue, and environmental fractures. The last chapter is dedicated to the use of fractography in determining of the causes component failure. In modern engineering, the analysis of fractured components is a common practice in many fields, such as integrity management systems, materials science research, and failure investigations. As such this book is useful for engineers, scientists, engineering students, loss adjuster surveyors and any professional dealing with fractured components.




Ultra-low-Cycle Fatigue Failure of Metal Structures under Strong Earthquakes


Book Description

This book presents experimental results and theoretical advances in the field of ultra-low-cycle fatigue failure of metal structures under strong earthquakes, where the dominant failure mechanism is ductile fracture. Studies on ultra-low-cycle fatigue failure of metal materials and structures have caught the interest of engineers and researchers from various disciplines, such as material, civil and mechanical engineering. Pursuing a holistic approach, the book establishes a fundamental framework for this topic, while also highlighting the importance of theoretical analysis and experimental results in the fracture evaluation of metal structures under seismic loading. Accordingly, it offers a valuable resource for undergraduate and graduate students interested in ultra-low-cycle fatigue, researchers investigating steel and aluminum structures, and structural engineers working on applications related to cyclic large plastic loading conditions.




Mechanical Properties of Materials


Book Description

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.




Post-Ductility


Book Description

The third book in the series from Columbia University is focused on metals. Metals, as surface or structure as the generators of space play a role in nearly every strain of modernization in architecture. They define complete geographies of work, production, and political life. Non-architectural metals delivered in automobiles, and hard goods in the United States and worldwide have all been sourced as the engines of the sprawling late twentieth-century city in all of its forms. But in the received aspects of architectural history, metals, and in particular steel, remain less diluted; they are presented as intrinsic to the profession as material precedes concepts they are carriers of architectural meaning. Few concepts are as central in structural engineering as the ability of a material to sustain plastic deformation under tensile stress the standardization of historically known deformation limits or ductile properties in most materials allows architects and engineers to keep the analysis of structure within known parameters of finite element analysis rather then materials science. If the goal is avoid fracture, the boundaries are set and the limits of ductility are observed. Post-Ductility refers to the literal aspects of material behavior in this case of metals but also of aspects of architectural and urban space that are measured by less verifiable but nonetheless real quotients of stress and strain. It is the tension and compression of space that gives form or coherence to form. In either the case of engineering and architecture, formerly daunting degrees of risk seem to have been diminished; new levels of sophistication in calculation lower the risk tolerance for fracture, while more metaphoric readings of limits in architectural and urban space seem to have been long surpassed, at times with abandon. The counter-effort has been quite strong if not successful: there are those that want to recreate dense cities by means of compression and there are immense forces of spatial extension by way of economics, communication and transit. Space is pulled to elastic limits and made thin as highly malleable materials such as gold or lead as it is also often re-compressed as forms of urban density. If metals are a significant origin for architecture and indeed whole cities—from buildings to automobiles and labor, then what are the limits or equations that offer a new evaluation of both metals, but also of material in a wider sense, as a determining component of the built world? What does an engineer and architect bring to this arena in both local and global circumstances?
