This book presents a self-contained and comprehensive look at the field of dynamic plasticity for researchers and graduates in mechanical engineering. Drawing on the author's long career in the field, the book greatly extends material from the 1967 original edition with the addition of fresh research chapters as well as a full introduction to the elementary theory of plasticity. The coverage of new areas includes a chapter on rocks and soils, the various developments in research on rate type, and novel problems concerning non-homogenous Bingham fluids, such as flow along an inclined slope. Other chapters consider the latest issues in metal working, such as drawing, floating plug, and extrusion. New problems concerning the perforation of plates with high velocity are also included.

The present book is the result of work carried out over a period of about ten years by the author and his co-workers in order to describe more accurately the slow irreversible deformation in time of the rocks surrounding underground openings. To begin with, our efforts were directed toward a better under standing of the mechanical behaviour of rocks and to the formulation of more precise mathematical models for their dominant mechanical properties, mainly irreversible dilatancy and/or compressibility during creep. Subsequent efforts were focused on finding improved solutions to important mining and oil engineering problems, such as, for instance, the creep of rocks around wells and tunnels, short-term failure which may occur around an underground opening, damage and failure which take place after long-time intervals, the tunnel support analysis incorporating rock creep, etc. The book is the result of a great number of questions posed either by mining engineers or by the author himself, and of the corresponding answers (unfor tunately often only partial answers). This dialogue must certainly be continued in order to improve the models and to formulate models for other kinds of rocks, or, ultimately to obtain solutions for other important engineering problems. It is hoped that the book will also contribute to a better description, by means of mathematical models, of the mechanical behaviour of rocks.

The world requires an increasing number of underground facilities for applications such as storage, waste repositories and traffic. Accurate prediction of the stability and deformation of these facilities is essential, and calls for model calculations using reliable and comprehensive constitutive equations describing the mechanical behaviour of the rocks involved, particularly the time-dependent effects. Here the authors combine their knowledge and personal experience in this field to encourage the practical use of material laws based on a sound physical and mathematical basis. Further discussion and research on the time-dependent behaviour of rocks and related materials is supported in the text by more than 200 figures. The text covers elasticity, creep, dilatancy, creep failure and short term failure, experimental techniques and test results, micromechanical deformation mechanisms, viscoplasticity and computation using appropriate constitutive equations, including many fundamental model calculations. Rock mechanics incorporates aspects of many disciplines including structural geology, soil mechanics, material sciences, civil, mining and petroleum engineering, seismology and geophysics. This book will therefore find a wide appreciation amongst engineers, researchers and graduate students in these and other related areas.

This is a comprehensive, reader-friendly treatment of the theory behind modern elastic composite materials. The treatment includes recently developed results and methods drawn from research papers published in Eastern Europe that until now were unavailable in many western countries. Among the book's many notable features is the inclusion of more than 400 problems, many of which are solved at the end of the book. Mechanics of Elastic Composites is an outstanding textbook for graduate-level course work and a valuable reference for engineers and researchers. Developed over many years by leading experts in the field, this book will remain an important contribution to the literature for years to come.
