The certification of the structural integrity of buildings, bridges, and mechanical components is one of the main goals of engineers. For civil engineers especially, understanding the tools available for infrastructure analysis is an essential part of designing, constructing, and maintaining safe and reliable structures. Fracture and Damage Mechanics for Structural Engineering of Frames: State-of-the-Art Industrial Applications outlines the latest computational tools, models, and methodologies surrounding the analysis of wall and frame load support and resilience. Emphasizing best practices in computational simulation for civil engineering applications, this reference work is invaluable to postgraduate students, academicians, and engineers in the field.

The development of NDT (non-destructive testing) techniques used for the inspection of concrete structures is currently in high demand, because many existing structures have become aged and deteriorated in service. In order to formulate predictions on their stability and to estimate their safety, it is necessary to identify damage signals and to determine their causes. In this regard, the development and establishment of innovative and highly advanced non-destructive methods are required. Acoustic Emission (AE) and related NDE (non-destructive evaluation) techniques have been extensively used to determine crack detection and damage evaluation in concrete. With the move towards a more sustainable society, and the need to extend the long-term service life of infrastructure and aging and disastrous damage due to recent earthquakes, Acoustic Emission (AE) and Related Non-destructive Evaluation (NDE) Techniques in the Fracture Mechanics of Concrete: Fundamentals and Applications is a critical reference source for civil engineers, contractors working in construction and materials scientists working both in industry and academia.

This book emphasises the physical and practical aspects of fatigue and fracture. It covers mechanical properties of materials, differences between ductile and brittle fractures, fracture mechanics, the basics of fatigue, structural joints, high temperature failures, wear, environmentally-induced failures, and steps in the failure analysis process. Separate chapters are devoted to fatigue and fracture of steels, aluminum alloys, titanium and titanium alloys, ceramics, polymers and continuous fiber polymer matrix composites.

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.

This book contains the papers presented at the ninth International Conference on Structures Under Shock and Impact. The shock and impact behaviour of structures is a challenging area, not only because of the obvious time-dependent aspects, but also because of the difficulties in specifying the external dynamic loading characteristics for structural designs and hazard assessments and in obtaining the dynamic properties of materials. Thus, it is important to recognise and utilise fully the contributions and understanding emerging from theoretical, numerical and experimental studies on structures, as well as investigations into the material properties under dynamic loading conditions. Featured topics include: impact and blast loading characteristics; material response to high rate loading; missile penetration and explosion; protection of structures from blast tools; behaviour of structural concrete; structural behaviour of composites; interaction between computational and experimental results; energy absorbing issues; structural crashworthiness; structural serviceability under impact loading; and seismic engineering applications.

The damage analysis of engineering materials and components is a prime concern in the durability assessment and integrity of engineering components in service. Engineering materials are routinely subjected to failure in a wide variety of applications in aeronautical, electronic, automotive, nuclear plant, petroleum and transportation industries. This book presents the fundamental elements and theories in fracture and damage analysis, plus the recent research and advances in the development of the analytical and practical approaches required to assess the materials damage and the durability of structures. The wide-ranging discussion on damage theories and practical issues in damage analysis will be of benefit to researchers, post-graduate students and engineers in practical sectors of durability and failure of materials and structures.

In this volume various integral equations for multiple crack problems in plane elasticity are investigated. Formulation of the problems is based on relevant elementary solutions in which the complex variable function method is used. The multiple crack problem is considered as a superposition of many single crack problems while many more complicated cases, including bonded dissimilar materials and multiple thermally insulated crack problems, are considered. Miscellaneous problems, including the multiple rigid line problem and the multiple circular hole problem are studied. Solutions for three-dimensional multiple crack problems are also investigated by using the Fredholm integral equation, the hypersingular integral equation and the variational principle. Many programs for multiple crack problems using FORTRAN are featured. A CD-ROM containing solutions is also included.

Engineering materials are subjected to fatigue loading in a wide variety of applications in the aeronautical, automotive, nuclear plant, petroleum and transportation industries. The extensive use of engineering materials over such a range of applications plus the cost involved in fatigue failure of materials and structures has resulted in an increasing awareness of the importance of damage and durability under cyclic loading conditions. Focusing on state-of-the-art advances in the development of methods to predict fatigue performance of materials and structures, this book contains papers from the First International Conference on Fatigue Damage of Materials. The coverage is broad and includes a range of materials and structures as well as different viewpoints and approaches to the fatigue analysis problem. The 45 contributions featured are divided under the following headings: case studies on fatigue; computational methods; low cycle fatigue; fatigue crack initiation; fatigue crack propagation; fatigue damage analysis; fatigue of welded joints; multiaxial fatigue; small crack growth and threshold; statistical analysis of fatigue; and thermo-Mechanical fatigue and creep.

Highly regarded text presents detailed discussion of fundamental aspects of theory, background and the idealizations on which it rests, with detailed solutions of typical and illustrative problems.

This wide-ranging survey of the physical aspects of fracture shows that the old barriers between different scales will soon themselves fracture. It is no longer unrealistic to imagine that a crack initiated through a molecular dynamics description could be propagated at the grain level thanks to dislocation dynamics included in a crystal plasticity model, itself implemented in a finite element code. Linking what happens at the atomic scale to fracture of structures as large as a dam is the new emerging challenge. The volume includes papers on most materials of practical interest from concrete to ceramics through metallic alloys, glasses, polymers and composite materials. The classical fields of fracture mechanisms are addressed. Brittle and ductile fractures are considered. The text is carefully balanced between experiments, simulations and theoretical models, and between the contributions by the various communities. New topics of damage and fracture mechanics are also explored, such as the effect of disorder and statistical aspects, dynamic fracture, friction and fracture of interfaces.

Intended for engineers, researchers, and graduate students dealing with materials science, structural design, and nondestructive testing and evaluation, this book represents a continuation of the author's "Fracture Mechanics" (1997). It will appeal to a variety of audiences: The discussion of design codes and procedures will be of use to practicing engineers, particularly in the nuclear, aerospace, and pipeline industries; the extensive bibliography and discussion of recent results will make it a useful reference for academic researchers; and graduate students will find the clear explanations and worked examples useful for learning the field. The book begins with a general treatment of fracture mechanics in terms of material properties and loading and provides up-to-date reviews of the ductile-britttle transition in steels and of methods for analyzing the risk of fracture. It then discusses the dynamics of fracture and creep in homogeneous and isotropic media, including discussions of high-loading-rate characteristics, the behavior of stationary cracks in elastic media under stress, and the propagation of cracks in elastic media. This is followed by an analysis of creep and crack initiation and propagation, describing, for example, the morphology and incubation times of crack initiation and growth and the effects of high temperatures. The book concludes with treatments of cycling deformation and fatigue, creep-fatigue fractures, and crack initiation and propagation. Problems at the end of each chapter serve to reinforce and test the student's knowledge and to extend some of the discussions in the text. Solutions to half of the problems are provided.

This book provides practicing engineers, researchers, and students, with a working knowledge of the fatigue damage processes and models under multiaxial state of stress and strain. Readers are introduced to the important considerations of multiaxial fatigue that differentiate it from uniaxial fatigue. Multiaxial Fatigue presents an interpretive summary and comparison of various classes of models, providing a complete treatment of the subject from many perspectives. The concepts presented in this book are material independent and will be useful in designing test programs for metallic, ceramic, composite, and other materials. The book is filled with examples, case studies, and diagrams to make it a useful learning tool as well as a valuable desk reference. Contents include: State of Stress and Strain Stress-Strain Relationships Fatigue Damage Mechanisms Multiaxial Testing Nonproportional Loading Notches Strain-Based and Energy-Based Models Stress-Based Models Fracture Mechanics Model Applications.

This text records the Proceedings of the IUTAM Symposium held in Cambridge in 1995. It contains 35 articles by leading authorities and addresses the modelling of fracture from a variety of perspectives, ranging over mechanics, material science, physics, geophysics, and nonlinear dynamics. The most important single practical question addressed is that of scale. This is considered in relation to nonlinear material behaviour, micromechanics and statistical variations, and the interaction of these aspects. Certain aspects of the subject have experienced significant advance, from one or other of the standpoints of physics, materials science or mechanics. This book is intended to contribute towards the wider dissemination of these advances and the development of a unified perspective. It will be useful to those active in research in fracture who wish to gain an overview of the subject, taking advantage of insights gained from the whole range of this expertise.

The field of stress analysis has gained its momentum from the widespread applications in industry and technology and has now become an important part of materials science. Various destructive as well as nondestructive methods have been developed for the determination of stresses. This timely book provides a comprehensive review of the nondestructive techniques for strain evaluation written by experts in their respective fields.

The main part of the book deals with X-ray stress analysis (XSA), focussing on measurement and evaluation methods which can help to solve the problems of today, the numerous applications of metallic, polymeric and ceramic materials as well as of thin-film-substrate composites and of advanced microcomponents. Furthermore it contains data, results, hints and recommendations that are valuable to laboratories for the certification and accreditation of their stress analysis.

Stress analysis is an active field in which many questions remain unsettled. Accordingly, unsolved problems and conflicting results are discussed as well. The assessment of the experimentally determined residual and structural stress states on the static and dynamic behavior of materials and components is handled in a separate chapter.

Students and engineers of materials science and scientists working in laboratories and industries will find this book invaluable.

High Temperature Mechanical Behavior of Ceramic Composites provides an up-to-date comprehensive coverage of the mechanical behavior of ceramic matrix composites at elevated temperatures. Topics include both short-term behavior (strength, fracture toughness and R-curve behavior) and long-term behavior (creep, creep-fatigue, delayed failure and lifetime). Emphasis is on a review of fundamentals and on the mechanics and mechanisms underlying properties.
This is the first time that complete information of elevated temperature behavior of ceramic composites has ever been compacted together in a single volume. Of particular importance is that each chapter, written by internationally recognized experts, includes a substantial review component enabling the new material to be put in proper perspective.
