      Plates and shells play an important role in structural, mechanical, aerospace and manufacturing applications. The theory of plates and shells have advanced in the past two decades to handle more complicated problems that were previously beyond reach. In this book, the most recent advances in this area of research are documented. These include topics such as thick plate and shell analyses, finite rotations of shell structures, anisotropic thick plates, dynamic analysis, and laminated composite panels. The book is divided into two parts. In Part I, emphasis is placed on the theoretical aspects of the analysis of plates and shells, while Part II deals with modern applications. Numerous eminent researchers in the various areas of plate and shell analyses have contributed to this work which pays special attention to aspects of research such as theory, dynamic analysis, and composite plates and shells.

      An extensive review of the theory of plasticity, limit design and limit analysis of plates is contained in this volume. Detailed descriptions are given on the plastic behaviour of homogeneous, reinforced and sandwich plates, and on the rise of various yield-line patterns. The volume differs from other books on the plastic analysis of plates by its comprehensive treatment of: the theory of yield fans connected with yield-line planning; the plastic behaviour of plates under combined loadings characterized by the load factors; statical solutions; and continuous, rectangular and skew plates.Before discussing the upper-bound solutions for various types of ultimate loads acting on isotropic, orthotropic and anisotropic plates, the kinematic conditions of the plastic behaviour of plates and the principles and methods of the yield-line theory are examined in detail. Generalized yield conditions of the second degree for orthotropic and anisotropic plates are introduced. Special attention is paid to the rise of yield fans. The concept of yield line planning is also discussed, which may be of practical interest since it indicates the possibilities for preventing the rise of yield fans. Upper-bound and lower-bound solutions for the ultimate uniform load, concentrated loads, triangular and trapexoidal loads, are presented. Similar solutions are provided for continuous loads bounded by various plane and curved surfaces and for various combinations of loads acting on rectangular, polygonal, circular, elliptic and skew plates. Solutions are given for plates on hinged supports, on free supports with elevating corners, on point supports and also for plates with built-in edges. Numerical tables are provided for determining the ultimate loads, bearing moments needed for the given load systems and the parameters of yield-line patterns. The procedures detailed in the volume will prove an indispensable reference source in the practical design of roof, ceiling and bridge slabs.

      This proceedings volume contains papers from researchers in Japan, the United States and England who have made fundamental contributions to the micromechanics of granular materials. The purpose of the seminar was to facilitate an exchange of ideas between scientists working with statistical and continuum theories, computer simulations and experiments on both static and dynamic behaviour. In describing the solid like behaviour of granular materials, many new ideas on the constitutive relations are introduced in this volume. As an application of the analysis, the mechanism of liquefaction is discussed. Computer simulations have become a vital tool in establishing the micromechanical approaches which otherwise would not be experimentally tested. In numerical simulations and theoretical analyses of rapid granular flow, various modifications on the nature of materials and boundaries are given. Possible applications of the techniques of the stereology and analysis based on geometrical statistics are also included. The papers collected in this volume signify that the promotion of a good understanding of the mechanics of granular materials has been and will continue to be valued in a variety of technical disciplines.

      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.

      Drawing on transit experience from various countries and markets, this book examines the economic environment of transit operations, the cost and production properties of transit service supply and the policies and prospects of transit regulatory reform. The principal objectives of the book are: first to conduct theoretical and empirical analyses of the major factors which jointly determine the economic structure and conditions of the transit sector; and second to explore and suggest policies which could resolve the sector's present crisis and make it economically viable. The first objective is explored in Part One where major structural demand factors and regulatory and subsidy conditions are identified and examined. Analytical and empirical measurement of technical production characteristics of transit services supply is carried out in Part Two. Part Three focuses on transit regulatory reform policy issues.The book is aimed primarily at an audience of transportation professionals, including economists and planners as well as public policy analysts. It requires, in general, a sound background in economics, mainly microeconomics. Thus graduate students in economics, geography, urban planning and public policy, and advanced undergraduates with good training in economics can best benefit from this book.

      Polyconjugated organic materials are revealing amorphous electrical and non-linear optical properties; this fact is opening up a whole new field of Materials Science aimed at the development of new technologies. For many years inorganic materials were studied mostly for non-linear optical properties. When organic molecules began to show larger and faster responses, both physical chemists and organic chemists became involved in understanding the physical phenomena at a molecular level, with the hope of synthesizing new and better molecular systems. The non-linear optical responses of this class of organic materials are presently attracting considerable attention as an active field of research both in academic and industrial laboratories.Due to the variety of problems and techniques involved, students and beginners with different backgrounds who approach polyconjugated materials do not find it an easy field to enter. This book introduces in a comprehensive and tutorial way the necessary concepts and relevant references which will help the reader to grasp the fundamental concepts of polyconjugated organic materials and perceive the relations between them.

      This book presents an empirically estimated applied general equilibrium model for India and the analysis of a wide range of policy issues carried out using the model. The various chapters in the book deal with public distribution policies, foreign trade and aid policies, rural works programmes, terms of trade policies, fertilizer subsidy policies and irrigation development policies. These policies are analysed in terms of their immediate and medium term effects on production, consumption and prices of different commodities, on the growth of the economy as well as on the distribution of income among different groups in rural and urban areas and the incidence of poverty in the economy. Each chapter dealing with policy analysis describes the analytical issues involved, the historical context and experience of the policy concerned, results of the model scenarios and the policy insights that emerge.
