This book describes formulations and computations of the BEM in transversely isotropic bi-material rocks. The work concentrates on the development of the BEM using the FORTRAN program, which are then applied to the two dimensional problems. This book is divided into six chapters. Chapter one defines the problem, introduce the undertaking of the study and outlines the method of approach adopted in this book. Chapter two provides an overview of linear elastic fracture mechanics studies of bi-material systems. Various solution techniques are introduced and studies concerning: (i) a crack lying along the interface, (ii) a crack terminating or crossing through an interface, and (iii) a wedge with its vertex on the interface are reviewed. In addition, a brief review of the numerical solution techniques, crack initial angle and the propagation path of the relevant literature. Chapter three provides a detailed account of the theoretical approach used to determine the stress and displacement fields using the boundary element method. This chapter includes the basic equations and fundamental solution of anisotropic elasticity, boundary element formulation, numerical discretization, stress intensity factor expression and the fracture propagation simulation. Chapter four proposes the determination of mixed mode stress intensity factors with the boundary element formulation. Numerical examples for determining the mixed mode stress intensity factors for several cracked materials are presented for isotropic and anisotropic media. Chapter five shows the experimental result of actual rocks and discussion, which includes the numerical results of the comparison with failure mechanism, the initial angle and the propagation path. Finally, Chapter six summarizes the findings and contribution of the current work.

An up-to-date and practical reference book on piping engineering and stress analysis, this book emphasizes three main concepts: using engineering common sense to foresee a potential piping stress problem, performing the stress analysis to confirm the problem, and lastly, optimizing the design to solve the problem. Systematically, the book proceeds from basic piping flexibility analyses, spring hanger selections, and expansion joint applications, to vibration stress evaluations and general dynamic analyses. Emphasis is placed on the interface with connecting equipment such as vessels, tanks, heaters, turbines, pumps and compressors. Chapters dealing with discontinuity stresses, special thermal problems and cross-country pipelines are also included. The book is ideal for piping engineers, piping designers, plant engineers, and mechanical engineers working in the power, petroleum refining, chemical, food processing, and pharmaceutical industries. It will also serve as a reference for engineers working in building and transportation services. It can be used as an advance text for graduate students in these fields.

This book reviews problems in the mechanical behaviour of cyclically loaded metallic materials, primarily with regard to the nature of the fatigue process. The first edition of the book appeared in 1980. The present second edition represents a revised form of the original book and also covers recent developments in the field. As the book focuses on physical-metallurgical aspects, it occupies a unique and important position in the technical literature, which has so far been devoted mainly to engineering metal fatigue problems and their technical solution in specific practical cases. The book provides a compact review of current knowledge on physical metallurgical processes that accompany and affect the fatigue of metallic materials, and also presents the background for applying the new results to practical designing and to the selection of materials in engineering practice.
The authors present an updated review of results from countries both in the east and the west and cover a relatively large field in a concise manner. The work will be of value to research workers and students following advanced and post-graduate courses in the fields of materials science and mechanical engineering.

This classic text of elementary dislocation theory has been reprinted to fulfil persistent demand. Yet because it approaches elementary dislocation theory from its most basic level, the material contained in the volume is as up-to-date as when first published. The text addresses topics which are fundamental to the theory of dislocation behaviour, such as Burgers vectors and internal stresses of dislocations.

Classical fracture mechanics that emerged during the 1920s has gained popularity via LEFM from the 1940s to the 1960s. The principles of classical fracture mechanics evolved from experimental observation of the behaviour of glass that contains pre-existing cracks and is largely supported by physical reasoning. Chapter One presents a robust analysis of problems encountered in the field of pipeline networks and boiler components as a result of structural imperfection. Chapter Two deals with an analytical model of cracking, which is induced by thermal stresses in a porous multi-particle-matrix system. This system consists of spherical pores and isotropic spherical particles, which are both periodically distributed in an isotropic infinite matrix. Chapter Three reports on an analytical model of cracking in a multi-particle matrix system with isotropic whiskers, which are periodically distributed in an isotropic infinite matrix.

The engineering necessity of fracture mechanics is to improve the empirical data-handbook style and mechanics of materials based design. This book examines the phenomenon of "crack growth". The contributed chapters in this book have been derived from various research groups' results from their experiments and/or simulations of crack growth in various media. The contributed chapters discuss the effect of inhomogeneity, plasticity effects in single crystals, interfaces and welded joints. The book gives a snapshot of the research effort of various groups around the globe in the past decade or more on the important topic of crack growth.

Explains why pipeline stress corrosion cracking happens and how it can be prevented

Pipelines sit at the heart of the global economy. When they are in good working order, they deliver fuel to meet the ever-growing demand for energy around the world. When they fail due to stress corrosion cracking, they can wreak environmental havoc.

This book skillfully explains the fundamental science and engineering of pipeline stress corrosion cracking based on the latest research findings and actual case histories. The author explains how and why pipelines fall prey to stress corrosion cracking and then offers tested and proven strategies for preventing, detecting, and monitoring it in order to prevent pipeline failure.

"Stress Corrosion Cracking of Pipelines" begins with a brief introduction and then explores general principals of stress corrosion cracking, including two detailed case studies of pipeline failure. Next, the author covers: Near-neutral pH stress corrosion cracking of pipelinesHigh pH stress corrosion cracking of pipelinesStress corrosion cracking of pipelines in acidic soil environmentsStress corrosion cracking at pipeline weldsStress corrosion cracking of high-strength pipeline steels

The final chapter is dedicated to effective management and mitigation of pipeline stress corrosion cracking. Throughout the book, the author develops a number of theoretical models and concepts based on advanced microscopic electrochemical measurements to help readers better understand the occurrence of stress corrosion cracking.

By examining all aspects of pipeline stress corrosion cracking--the causes, mechanisms, and management strategies--this book enables engineers to construct better pipelines and then maintain and monitor them to ensure safe, reliable energy supplies for the world.

Since the development of linear elastic fracture mechanics (LEFM) decades ago, its limitations have been discussed extensively. Methods of manipulation on how to overcome the problems have been proposed by many enthusiasts. This book also highlights the limitation and at the same time proposes solutions. The effect of fracture on the structure of nano-catalyst and diamond-like carbon coating de-lamination are some of the microscopical research covered in this book. The format of this book is such that the reader can use each chapter independently. It starts with the first chapter outlining the classical review that traces back to early fracture mechanics. It is then continued to broader ranges from experimental and commercial software implementation, to the formulation and implementation of XFEM and piezoelectricity problems.

Fatigue is one of the primary reasons for the failure of structural components. The life of a fatigue crack has two parts, initiation and propagation. Dislocations play a major role in the fatigue crack initiation phase. It has been observed in laboratory testing that after a large number of loading cycles dislocations pile up and form structures called persistent slip bands (PSB). Fatigue crack growth is a crucial subject in the aircraft, railroad and other transportation industries as well as in the biomedical industry. This book presents the latest research in the field.

This textbook provides an accessible and self-contained description of the Galerkin finite element method for the two important models of continuum mechanics, transient heat conduction and elastodynamics, from formulation of the governing equations to implementation in Matlab. The coverage follows an intuitive approach: the salient features of each initial boundary value problem are reviewed, including a thorough description of the boundary conditions; the method of weighted residuals is applied to derive the discrete equations; and clear examples are introduced to illustrate the method.

A translation of "Raschet Stroitel 'Nikh Konstruktsii Uchetom Polzuchesti," published in Moscow in 1988. This is a presentation of the general principles and methods of design of continuous solid bodies and elemental reinforcement systems in materials which possess creep and ageing properties.

This unified guide brings together the underlying principles, and predictable material responses, that connect metals, polymers, brittle solids and energetic materials as they respond to extreme external stresses. Previously disparate scientific principles, concepts and terminology are combined within a single theoretical framework, across different materials and scales, to provide all the tools necessary to understand, and calculate, the responses of materials and structures to extreme static and dynamic loading. Real-world examples illustrate how material behaviours produce a component response, enabling recognition and avoidance of the deformation mechanisms that contribute to mechanical failure. A final synoptic chapter presents a case study of extreme conditions brought about by the infamous Chicxulub impact event. Bringing together simple concepts from diverse fields into a single, accessible, rigourous text, this is an indispensable reference for all researchers and practitioners in materials science, mechanical engineering, physics, physical chemistry and geophysics.
