  • Micromechanics

    Overall Properties of Heterogeneous Materials
    • 1st Edition
    • Volume 37

    A comprehensive overview is given in this book towards a fundamental understanding of the micromechanics of the overall response and failure modes of advanced materials, such as ceramics and ceramic and other composites. These advanced materials have become the focus of systematic and extensive research in recent times. The book consists of two parts. The first part reviews solids with microdefects such as cavities, cracks, and inclusions, as well as elastic composites. To render the book self-contained, the second part focuses on the fundamentals of continuum mechanics, particularly linear elasticity which forms the basis for the development of small deformation micromechanics.In Part 1, a fundamental and general framework for quantitative, rigorous analysis of the overall response and failure modes of microstructurally heterogeneous solids is systematically developed. These expressions apply to broad classes of materials with inhomogeneities and defects. While for the most part, the general framework is set within linear elasticity, the results directly translate to heterogeneous solids with rate-dependent or rate-independent inelastic constituents. This application is specifically referred to in various chapters. The general exact correlations obtained between the overall properties and the microstructure are then used together with simple models, to develop techniques for direct quantitative evaluation of the overall response which is generally described in terms of instantaneous overall moduli or compliance. The correlations among the corresponding results for a variety of problems are examined in great detail. The bounds as well as the specific results, include new observations and original developments, as well as an in-depth account of the state of the art.Part 2 focuses on Elasticity. The section on variational methods includes some new elements which should prove useful for application to advanced modeling, as well as solutions of composites and related heterogeneous bodies. A brief modern version of elements in vector and tensor algebra is provided which is particularly tailored to provide a background for the rest of this book.The data contained in this volume as Part 1 includes new results on many basic issues in micromechanics, which will be helpful to graduate students and researchers involved with rigorous physically-based modeling of overall properties of heterogeneous solids.

  • Spatial Analysis and Planning under Imprecision

    • 1st Edition
    • Y. Leung
    • Ake E. Andersson
    • English
    The book deals with complexity, imprecision, human valuation, and uncertainty in spatial analysis and planning, providing a systematic exposure of a new philosophical and theoretical foundation for spatial analysis and planning under imprecision. Regional concepts and regionalization, spatial preference-utility-c... structures, spatial optimization with single and multiple objectives, dynamic spatial systems and their controls are analyzed in sequence.The analytical framework is based on fuzzy set theory. Basic concepts of fuzzy set theory are first discussed. Many numerical examples and empirical studies are provided to substantiate the theoretical arguments and empirical relevance of this approach.The book provides a more comprehensive perspective on uncertainty and a flexible framework for analysis in the real world, for problems such as commonly encountered spatial problems, urban and regional economic problems, and planning problems. Though the treatment is unconventional, it generally includes conventional analyses as special cases.

  • Stabilization Policy in France and the Federal Republic of Germany

    • 1st Edition
    • Volume 153
    • G. de Ménil + 1 more
    • English
    The object of this book is to compare the macroeconomic characteristics of the French and German economies. It focusses on the effect of stabilization policy and of international disturbances and tries to find out the trade-offs of economic policy. The study is based on a simulation analysis using large-scale econometric models of the two countries. Instead of using models as black boxes the dynamic structures are compared in considerable detail. This entails decomposing the models into blocs of strategic sets of equations. Comparing bloc by bloc allows one to distinguish between the contribution of various economic processes (price-wage dynamics, monetary mechanism, multiplier-accelerat... interaction) to macroeconomic performance.Main features: Franco-German comparison of macroeconomic response to policy measures and international shocks; Evaluation of policy trade-offs; Detailed institutional and historical background to macro-policy in France and Germany.

Papers dealing with the vibration and the dynamic response of thin elastic bodies are also presented.A strong emphasis is made on the practical applications aspect in the theories presented. Thus engineers, research workers and students who are involved with the design and analysis of shell structures made of different materials, and subjected to various static and dynamic loads will find this volume an invaluable source of reference.

  • Handbook of Studies on Depression

    • 1st Edition
    • Graham D. Burrows
    • English
    Handbook of Studies on Depression is a collection of papers on the research and general overview of studies on depression from many countries of the world. Divided into four sections, the handbook presents an international coverage of depression, which is becoming a major worldwide clinical problem. Section I is a collection of studies in classification, phenomenology, etiology of depression, and the classification of depression and response to treatments. The genetic factors contributing to depression, effects on children, and the affective symptoms in non-western countries are described. Section II focuses on studies in the treatment of depression, examining the modes of actions of antidepressants, the use of electroconvulsive treatment, and psychosurgery for depressive illnesses. Section III moves forward to the research made on depression, including problems in clinical research, the discovery of effective antidepressant and antimanic drugs, and research into clinical psychoendocrinology, particularly on the function of the adrenal cortex in depression. Concluding this section is a paper on which depression includes a broad spectrum of psychopathology, making biological research more difficult. The last section is a discussion on the aspects of depression. Common topics examined are the management of bereavement; suicide; the side effects of tricyclic antidepressants on cardiac function; and the management of drug over dosage, especially those acts associated with depression. Psychologists, psychiatrists, medical students, school counselors, marriage guidance counselors, select members of the police force, and even parents who are interested in the subject of depression will find this handbook both useful and informative.

  • Neurobionics

    An Interdisciplinary Approach to Substitute Impaired Functions of the Human Nervous System
    • 1st Edition
    • H.-W. Bothe + 2 more
    • English
    The goal of neurobionics is to elaborate methods for the repairment and substitution of impaired functions of the human nervous system. This publication contains contributions from internationally recognized scientists exploring the structure of this novel interdisciplinary research field. The structure consists of theoretical sciences (philosophy, mathematics, neuroinformatics, computational neuroscience), basic biological sciences (molecular biology, cell biology, biological network neuroscience, neurophysiology), technical engineering (microelectronics, micromechanics, robotics, microsystems), and clinical neurosciences (neurodiagnostics, neurology, neurosurgery, neurorehabilitation)... It is hoped the book indicates that a new kind of partnership across these various disciplines is mandatory if emerging problems in the field are to be solved. It also aims to set the coordinates for an international and interdisciplinary research field dealing with a subject intrinsic to man's mind and its biological carrier which may be partially replaced by artificial means in the future.

  • Continuum Mechanics of Electromagnetic Solids

    • 1st Edition
    • Volume 33
    • G.A. Maugin
    • J. D. Achenbach
    • English
    This volume is a rigorous cross-disciplinary theoretical treatment of electromechanical and magnetomechanical interactions in elastic solids. Using the modern style of continuum thermomechanics (but without excessive formalism) it starts from basic principles of mechanics and electromagnetism, and goes on to unify these two fields in a common framework. It treats linear and nonlinear static and dynamic problems in a variety of elastic solids such as piezoelectrics, electricity conductors, ferromagnets, ferroelectrics, ionic crystals and ceramics. Chapters 1-3 are introductory, describing the essential properties of electromagnetic solids, the essentials of the thermomechanics of continua, and the general equations that govern the electrodynamics of nonlinear continua in the nonrelativistic framework (e.g. Maxwell's equations, the fundamental balance laws of continuum mechanics, basic thermodynamical inequalities for electromagnetic continua, jump relations for studying the propagation of shock waves, nonlinear constitutive equations for large classes of materials).The remainder of the text presents in detail special cases, applications, solved problems, and more complex schemes of electromagnetic matter. Chapters 4 and 5 examine material schemes whose description relies on the above-mentioned equations. Chapters 6 and 7 are more advanced, reporting on recent progress in the field.Suitable for graduate teaching, the volume will also be useful to research workers and engineers in the field of electromagnetomechan... interactions, and to those interested in the basic principles, mathematical developments and applications of electroelasticity and magnetoelasticity in a variety of solid materials, such as crystals, polycrystals, compounds and alloys.
