Summary:

This guide was commissioned by the Institution of Civil Engineers and the Building Research Establishment to provide practical guidance for homeowners whose properties have been affected by subsidence, or heave, or who are concerned by the potential risk of damage. The first, best-selling, edition dealt specifically with the problems associated with properties founded on shrinkable clay soils, and was reprinted many times. The second edition has been expanded to include sections on other types of subsidence and causes of damage that are unrelated to foundation movement. It also looks at the potential problems that can arise when buying or selling a property that has previously been affected by subsidence.

Summary:

This new book on the fracture mechanics of concrete focuses on the latest developments in computational theories, and how to apply those theories to solve real engineering problems. Zihai Shi uses his extensive research experience to present detailed examination of multiple-crack analysis and mixed-mode fracture. Compared with other mature engineering disciplines, fracture mechanics of concrete is still a developing field with extensive new research and development. In recent years many different models and applications have been proposed for crack analysis; the author assesses these in turn, identifying their limitations and offering a detailed treatment of those which have been proved to be robust by comprehensive use. After introducing stress singularity in numerical modelling and some basic modelling techniques, the Extended Fictitious Crack Model (EFCM) for multiple-crack analysis is explained with numerical application examples. This theoretical model is then applied to study two important issues in fracture mechanics - crack interaction and localization, and fracture modes and maximum loads. The EFCM is then reformulated to include the shear transfer mechanism on crack surfaces and the method is used to study experimental problems. With a carefully balanced mixture of theory, experiment and application, Crack Analysis in Structural Concrete is an important contribution to this fast-developing field of structural analysis in concrete. Latest theoretical models analysed and tested Detailed assessment of multiple crack analysis and multi-mode fractures Applications designed for solving real-life engineering problems

Summary:

Do you yearn to find the real meaning to life or an inner peace that is true? Are you fed up with wearing a mask? Is life really getting you down? That is exactly where Colin Murray was just a few years ago. He invites you to travel with him through his life while he paints a vivid picture, reflecting on his childhood in Scotland, describing his happy, at times haphazard, life in the North East coastal town of Portsoy. He shares his experiences, going beyond the ‘safety’ of home, in search of personal fulfilment. You will witness him wearing an assortment of stereotypical hats: the hat of the wise-cracking bar fly, the guilt-ridden wrongdoer, the compulsive business builder, passionate protagonist, and even the wronged dupe. He admits that attempting to explain his personal quest for the truth has been extremely difficult, because so much of his journey involves those mystical inner feelings that lie beyond the horizon of words.The complicated paths and winding roads we follow are vast and varied, but we all reach a time in our lives when we want to know, at the deepest level, if our existence and our Soul are compatible. This book simply chronicles the quest for this fundamental truth.

Summary:

The Allied campaign for Northwest Europe as seen from a British and Canadian perspective A reinterpretation of the British Army's conduct in the crucial 1944-45 Northwest Europe campaign, this work examines the "Colossal Cracks" operational technique employed by Field Marshal Bernard Montgomery's Anglo-Canadian 21st Army Group. Rooted in concerns about morale and casualties, "Colossal Cracks" was a cautious, firepower-laden approach that involved the concentration of massive force at points of German weakness. Hart argues that Montgomery and his two senior subordinates handled this formation more effectively than some scholars have suggested and that "Colossal Cracks" represented the most appropriate weapon the British Army could develop under the circumstances.

Summary:

Composites offer great promise as light weight and strong materials for high performance structures. One of the major advantages of these materials as compared with metals is the basic way in which heterogeneity resist crack extension. In a fiber/matrix composite system, the fibers tend to cause cracks to form at closer spacing and delay the formation of a large crack. The enhancement of local failure such as fiber breaking, matrix cracking and interface debonding further reduces the energy level which might have otherwise reached the point of catastrophic failure. Even though substantial tests have been made on composite materials, little has been gained in the understanding and development of a predic tive procedure for composite failure. There are fundamental difficulties associated with incorporating the nonhomogeneous and anisotropic prop erties of the composite into the continuum mechanics analysis. Additional uncertainties arise from voids and defects that are introduced in the composite during manufacturing. Even a small quantity of mechanical imperfections can cause a marked influence on the composite strength. Moreover, the interface properties between the fibers and matrix or bonded laminae can also affect the load transmission characteristics significantly. It would be impossible to establish predictive procedures for composite failure unless realistic guidelines could be developed to control the manufacturing quality of composite systems.

Summary:

The present short monograph concerns analytic and semi-analytic techniques for finding an approximate value of the limit load. The limit load is an essential input parameter of flaw assessment procedures. In most cases, finding the limit load involves some numerical calculations of different levels of complexity, including numerical minimization of functions of one or several arguments, the slip-line technique and the finite element method. This book shows in particular how to use singular behavior of the real velocity field in the vicinity of bi-material interfaces in kinematically admissible velocity fields to increase the accuracy of upper bound solutions. An approach to recalculate the limit load for a class of structures with defects with the use of its value for the corresponding structure with no defect is discussed. The upper bound technique is applied to evaluate the limit load of overmatched and undermatched welded joints with cracks subject to various loading conditions of practical importance in conjunction with the aforementioned special techniques.

Summary:

Recent comparative, interdisciplinary scholarship has underscored the Inquisition s function in the imperial and colonial Iberian world, particularly in relation to the development of modernity. This book illustrates and enhances these debates on the Inquisition s relationship to imperialism, colonialism, and modernity through specific case studies of New Christians who became the target of the Inquisition. Drawing on research in the archives of the Spanish and the Portuguese Inquisition in different parts of the Iberian Atlantic World, it analyzes literary writings and inquisitorial testimonies produced by individuals of Jewish heritage who lived in the Iberian Atlantic world during the sixteenth, seventeenth and eighteenth centuries, and brings to light the direct and mediated discourse produced by New Christians, revealing the still veiled contributions of an important but understudied ethnic and social group.

Summary:

Restraint and intrinsic stresses in concrete at early ages are vitally important for concrete structures which must remain free of water-permeable cracks, such as water-retaining structures, tunnel linings, locks and dams. The development of hydration heat, stiffness and strength, also the degree of restraint and, especially for high-strength concrete, non-thermal effects, are decisive for sensitivity to cracking. Determining thses stresses in the laboratory and in construction components has led to a clearer understanding of how they develop and how to optimize mix design, temperature and curing conditions. New testing equipment has enabled the effects of all the important parameters to be qualified and more reliable models for predictiong restraint stresses to be developed. Thermal Cracking in Conrete at Early Ages contains 56 contributions by leading international specialists presented at the RILEM Symposium held in October 1994 at the Technical University of Munich. It will be valuable for construction and site engineers, concrete technologists and scientists.

Summary:

The use of cement bound material roadbases in flexible composite pavements in the United Kingdom is limited by the reflective cracking that occurs due to thermal shrinkage. Induced cracking is intended to diminish the effect of reflective cracking, thus enabling the thickness of the flexible layers to be reduced and consequently increase the competitiveness of flexible composite pavement due to initial construction cost savings and increased pavement life. This report presents an update on current worldwide research on the subject, together with a description of the construction of full-scale trials and initial monitoring that took place to evaluate the effectiveness of induced cracking in the UK. A discussion of the promising results is provided together with recommendations, including a draft specification, for further use of induced cracking in the UK.

Summary:

The purpose of Fitness-for-Service Fracture Assessment of Structures Containing Cracks is to facilitate the use of fracture mechanics based failure assessment procedures for the evaluation and design of structures and components. All practical structures contain flaws and the optimum combination of cost efficiency and safety whilst achieving the required capability, can only be realised by using state of the art methods such as that represented by the European flaw assessment method SINTAP/FITNET to analyse the safety risk. This book is written by practitioners with extensive experience in both the development and use of integrity assessment methods and provides comprehensive information on the basic principles and use of analytical flaw assessment. It provides an introduction to the method, its background, how it can be applied, its potential and, importantly, its limitations. The explanations are complimented by using a large number of worked examples and validation exercises which illustrate all aspects of the procedure. In addition, for students and engineers who are new to the subject, a comprehensive glossary of basic terms used in fracture mechanics based integrity evaluations is included. The topics addressed include: Crack driving force (CDF) and failure assessment diagram (FAD) type analyses Preparation of the input parameters (crack dimensions, stress-strain properties, fracture toughness, statistical aspects) Determination of the model parameters, (stress intensity factor and yield load solutions) Treatment of combined primary and secondary loading, together with residual stress effects Analysis of the effect of constraint effects (treatment of small defects and section size effects) Treatment of mixed mode loading Consideration of the influences of strength mismatch Reliability aspects Comprehensive description of the use of structural integrity methods to optimise cost effectiveness and safety Detailed description of how to evaluate the integrity of structures containing cracks Valuable background information for understanding the methods, their potential and limitations Large number of worked examples, which demonstrate all aspects of the methods Descriptive, readable writing style Applicable to a wide range of interests, from the student (university or self study) to the expert who requires a 'state of the art' document

Summary:

Fatigue failure is a multi-stage process. It begins with the initiation of cracks, and with continued cyclic loading the cracks propagate, finally leading to the rupture of a component or specimen. The demarcation between the above stages is not well-defined. Depending upon the scale of interest, the variation may span three orders of magnitude. For example, to a material scientist an initiated crack may be of the order of a micron, whereas for an engineer it can be of the order of a millimetre. It is not surprising therefore to see that investigation of the fatigue process has followed different paths depending upon the scale of phenomenon under investigation. Interest in the study of fatigue failure increased with the advent of industrial ization. Because of the urgent need to design against fatigue failure, early investiga tors focused on prototype testing and proposed failure criteria similar to design formulae. Thus, a methodology developed whereby the fatigue theories were proposed based on experimental observations, albeit at times with limited scope. This type of phenomenological approach progressed rapidly during the past four decades as closed-loop testing machines became available.

Summary:

The purpose of this Handbook is to provide a review of the knowledge and experiences in the field of fatigue fracture mechanics. It is well-known that engineering structures can fail due to cyclic loading. For instance, a cyclically time-varying loading reduces the structure strength and can provoke a fatigue failure consisting of three stages: (a) crack initiation (b) crack propagation and (c) catastrophic failure. Since last century many scientists have tried to understand the reasons for the above-mentioned failures and how to prevent them. This Handbook contains valuable contributions from leading experts within the international scientific community and covers many of the important problems associated with the fatigue phenomena in civil, mechanical and nuclear engineering.

Summary:

This book is concerned with the numerical solution of crack problems. The techniques to be developed are particularly appropriate when cracks are relatively short, and are growing in the neighbourhood of some stress raising feature, causing a relatively steep stress gradient. It is therefore practicable to represent the geometry in an idealised way, so that a precise solution may be obtained. This contrasts with, say, the finite element method in which the geometry is modelled exactly, but the subsequent solution is approximate, and computationally more taxing. The family of techniques presented in this book, based loosely on the pioneering work of Eshelby in the late 1950's, and developed by Erdogan, Keer, Mura and many others cited in the text, present an attractive alternative. The basic idea is to use the superposition of the stress field present in the unfiawed body, together with an unknown distribution of 'strain nuclei' (in this book, the strain nucleus employed is the dislocation), chosen so that the crack faces become traction-free. The solution used for the stress field for the nucleus is chosen so that other boundary conditions are satisfied. The technique is therefore efficient, and may be used to model the evolution of a developing crack in two or three dimensions. Solution techniques are described in some detail, and the book should be readily accessible to most engineers, whilst preserving the rigour demanded by the researcher who wishes to develop the method itself.
