The idea is to bring both the mechanics and physics on the micro scopic level to the macroscopic scale, so that the deformation and fracture processes of materials can be better understood. While much apparently remains to be done, this approach has already shed new light on certain selected topics and has proved to be fruitful. It is indeed a happy occasion to celebrate both Toshio's upcoming 65th birthday and the emergence of this young science at the same time. The volume contains thirty-seven original articles on the related topics of micromechanics and inhomogeneity; it is presented to Toshio by his friends, colleagues, and admirers as a wish for his good health and continuing pro ductivity. The contributors belong to both the applied mechanics and the materials communities, all with a common belief that micromechanics is an indispensable area of research. It is hoped that this somewhat balanced structure will make the volume more useful to a wider range of readers, and that in the meantime it will still reflect more or less the spectrum of Toshio's lifelong works. As Editors we have at the outset set the highest possible standards for the book, with a keen anticipation that the volume will be widely circulated for many years to come. We consider it an honor to have the opportunity to edit this volume. In the process of preparation, Toshio has been most helpful in providing all the needed information. We are grateful to the individual authors for their ready cooperation, and especially to Professor Mori for his efforts in writing the Toshio Mura Biography. The planning of this publication is also accompanied by a Symposium on Micromechanics and Inhomogeneity during the 1989 Winter Annual Meeting of the American Society of Mechanical Engineers in San Francisco. A total of sixty papers, including these thirty-seven, will be presented there. The other twenty-three papers, due to the constraints oftime and other factors, regrettably could not be included here. A list of these twenty-three papers is appended at the end of the Preliminary matter; they vi Preface are available directly from the authors to whom we also extend our appre ciation. In this regard Professors M. Eisenberg, H. Kobayashi, T. Mori, and E. Tsuchida have also served on the Organizing Committee. The symposium was cosponsored by the Constitutive Equations Committee, the Applied Mechanics Division and Materials Division of ASME, and the Japanese Society of Mechanical Engineers. Our special thanks are due to Springer-Verlag, New York, Inc., and its most capable and professional staff for their editing and production. The financial support of the Urakami Foundation for some overseas participants to the Mura Symposium is also gratefully acknowledged. Finally, we would like to express our appreciation to Mr. Shoji of Tohoku University for his help in the indexing of this book. Piscataway, New Jersey G.J. WENG Seattle, Washington M.
