PLASTICITY AND GEOMECHANICS

Authors：
r. o. davis is Professor of Civil Engineering at the University of Canterbury.
a. p. s. selvadurai is Professor of Civil Engineering and Applied Mechanics
at McGill University. Both authors are dedicated educators and researchers
in the fields of geotechnical engineering and geomechanics with a combined
experience exceeding 50 years. They are joint authors of the well-received Elasticity
and Geomechanics published in 1996 by Cambridge University Press, and
Professor Selvadurai is also the author of the two-volume monograph Partial
Differential Equations in Mechanics (2000).

Plasticity theory is widely used to describe the behaviour of soil and rock in
many engineering situations. Plasticity and Geomechanics presents a concise
introduction to the general subject of plasticity with a particular emphasis on
applications in geomechanics. Metal plasticity is described and elementary
theories are discussed before attention is focused specifically on geomaterials.
The greater part of the book is devoted to the classical aspects of plasticity,
particularly the use of upper and lower bound theorems and slip line theory.
Critical state theory is introduced and Cam Clay is described in detail.
Derived from the authors’ own lecture notes, this book is written with students
firmly in mind; the main body of the work is concerned with applications, while
the more theoretical aspects such as proofs of theorems are placed in appendices.
Excessive use of mathematical methods is avoided in the main body of the text
and, where possible, physical interpretations are given for important concepts.
In this way the authors present a clear introduction to the complex ideas and
concepts of plasticity as well as demonstrating how this developing subject is
of critical importance to geomechanics and geotechnical engineering.
Although entirely self-contained, this book constitutes a companion volume
to the acclaimed Elasticity and Geomechanics by the same authors, and will
appeal to students and researchers in the fields of civil, mechanical, material
and geological engineering. It may be used as a text for senior-level undergraduate
and graduate courses in soil mechanics, foundation engineering and
geomechanics.
