Hydraulic fracturing has been and continues to be a major techno- logical tool in oil and gas recovery, nuclear and other waste disposal, mining and particularly in-situ coal gasification, and, more recently, in geothermal heat recovery, particularly extracting heat from hot dry rock masses.

In this monograph I record those parts of the theory of transverse isotropic elastic wave propagation which lend themselves to an exact treatment, within the framework of linear theory.

Interest in acoustics continues to increase.

Concrete has traditionally been known as a material used widely in the construction of roads, bridges and buildings.

In this volume on the mechanics of fracture of Portland cement concrete, the general theme is the connection between microstructural phenomena and macroscopic models.

An International Conference on the Application of Fracture Mechanics to Ma- terials and Structures was held at the Hotel Kolpinghaus in Freiburg, West Ger- many, June 20-24, 1983.

This is a treatment of a number of aspects of the theory of hydrody- namic propulsion.

This volume contains the lectures presented at the NATO Advanced Study Institute that took place at the University of Delaware, Newark, Delaware, July 18-27, 1982.

This is not just another book on fracture mechanics.

The general objective of the Tenth Canadian Fracture Conference was to respond to progress in the engineering sciences - in particular with r- pect to rapidly developing new trends in the theory and methodology of researcr and designing - and to the resulting needs of practical engineering in the specific field of fracture mechanics and related areas of engineering mechanics.

This book contains the proceedings of a workshop on the Theoretical Founda- tion for Large-Scale Computations of Nonlinear Material Behavior, held under the auspices of the National Science Foundation (NSF) and the Defense Advance Re- search Projects Agency (DARPA), at Northwestern University, October 24-26, 1983.

The tremendous progress in astronomical observations over the past sixty years has revealed a vast structured universe whose fundamental parti- cles are galaxies, and clusters thereof.

From time to time the International Journal of Fracture has presented matters thought to be of special interest to its readers.

Portland cement concrete is a relatively brittle material.

This volume contains the full proceedings of the Fourth Advanced Study Institute organised by myself and my colleagues in .

The understanding of time dependent crack propagation processes occupies a central place in the study of fracture.

In the last decade the development in vibration analysis was char- acterized by increasing demands on precision and by the growing use of electronic computers.

This is a textbook on classical mechanics at the intermediate level, but its main purpose is to serve as an introduction to a new mathematical language for physics called geometric algebra.

This book contains the lectures of the 5th Advanced Seminar on Fracture Mechanics (ASFM 5) held at the Joint Research Centre, Ispra, on 14-18 October 1985.

While currently available texts dealing with the subject of high perfor- mance composite materials touch upon a spectra of topics such as mechanical metallurgy, physical metallurgy, micromechanics and macro- mechanics of such systems, it is the specific purpose of this text to examine elements of the mechanics of structural components composed of composite materials.

For protophysics, the fascinating and impressive constructive re-establish- ment of the foundations of science by Professor Paul Lorenzen, working with his colleagues and students of the Erlangen School, no task is more central than to.

This report describes the work performed by Lockheed Palo Alto Research Labora- tory, Palo Alto, California 94304.

In recent years, mathematical modelling allied to computer simulation has emerged as en effective and invaluable design tool for industry and a discipline in its own right.

Following Volumes III and IV that dealt with the fracture mechanics of concrete emphasizing both material testing and structural application in general, it was felt that specimen size and loading rate effects for concrete require further attention.

When asked to start teaching a course on engineering fracture mechanics, I realized that a concise textbook, giving a general oversight of the field, did not exist.

This book is, in essence, an updated and revised version of an earlier textbook, Newtonian Mechanics, written about fifteen years ago by one of us (APF) and published in 1971.

The Milky Way Galaxy offers a unique opportunity to study the structure and contents of a major stellar system in three dimensions, at high spatial and spectral resolution, and to very large galactocentric distances.

This volume contains papers presented at the NATO Advanced Research Workshop on the Structure and Dynamics of Partially Solidified Systems held at Stanford Sierra Lodge, Tahoe, California, May 12-16, 1986.

This book is written primarily for Earth scientists faced with problems in thermo- mechanics such as the flow and evolution of ice-sheets, convection currents in the mantle, isostatic rebound, folding of strata or collapse of cavities in salt domes.

The topic of "e;structural control"e;, which had already experienced some attention through publications, for example by Roorda, Yao, Yang, Abdel-Rohman, Leipholz etc.

Within the Solid Mechanics Program at the Office of Naval Research (ONR), our primary mission is to establish a basic research program which addresses the funda- mental issues in solid mechanics where a clear scientific understanding is lacking.

The first International Symposium on Shipboard Acoustics, held in Noordwijkerhout (The Netherlands) in 1976, was a meeting of invited experts, each having considerable expertise in ship acoustics.

Any practitioner who takes his profession in earnest, such that daily work is not a heavy duty but part of their life, will recognize in this book the rigorousness of the analysis and the comprehensive presentation of the problems.

This book stems from a course on Micromechanics that I started about fifteen years ago at Northwestern University.

The Symposium was held at the Great Wall Sheraton Hotel in Beijing, China in the period August 25-30, 1986.

This book is based on a number of lectures presented at CISM* -Course on "e;Stochastic Methods in Structural Mechanics"e;, August 28 -30,1985 in Udine, Italy.

This book originally appeared as a text prepared for the Defense Nuclear Agency to summarize research on dynamic pulse buckling, by the authors and their colleagues at SRI International, during the period from 1960 to 1980.

The origin of this book can be traced to a Workshop held at the University of Cambridge in December 1985 under the auspices of the Wolfson Group for Studies of Fluid Flow and Mixing in Industrial Processes.
