Typesetting: Camera ready by authors 61/3020-543210- Printed on acid-free paper Preface Plates and shells constitute a large class of surface type of structures with one of their dimensions, their thickness, much smaller than the other two dimensions. The analysis of the be­ havior of these structures under static and dynamic loads of great interest to scientists and engineers both from theoretical and the practical viewpoint. Indeed, is the the analysis of these structures represents a very challenging and attracti­ ve theoretical problem, as well as a problem of great practi­ cal significance, associated with applications in many enginee­ ring fields, such as civil, mechanical, aerospace, etc. It is the well known that numberical methods of solution, such as Finite Difference Element Method sing this and Method (FDM) and especially the Finite (FEM) are class of loading conditions During the has emerged of various some the only practical means for analy­ surface structures under complex boundary and/or realistic last 20 years the as a powerful tool complex problems material Boundary Element for the behavior. Method (BEM) numerical of mechanics. This solution method has distinct advantages over domain type techniques, such as the FDM and the FEM for a wide class of structural analysis problems. Information concerning the application of the BEM to plate and shell short sections or the BEM analysis can chapters in be found in the form of rather a number of books devoted to and its applications to various fields of engineering science and mechanics. These sections or chapters, however, deal mainly with static analysis of plates and shells and do not cover the more recent exciting developments in the area. No specific book plates and dealing exclusively shells by with the analysis of the BEM and covering all the aspects of their behavior up to date exists in the literature. The present book represents an effort to fill this gap in the literature by combining tutorial and state-of-the-art of the BEM as applied to plates and shells. aspects It aims at infor­ ming scientists and engineers engaged in the analysis of VI surface type of structures, about the use and the advantages of this technique, the most recent developments in the field and the pertinent literature for further study. The reader is expected to have a basic knowledge of plate and shell theory and applied mathematics. The book is divided into nine very well known for cover all the aspects existing to chapter to the basic literature.
