BOOK REVIEW
Fracture Mechanics, An Introduction(Second Edition)By E.E. Gdoutos, Springer, 369 pp., £96, ISBN 1-4020-
2863-6, 2005
Those working in the field of experimental mechanics
will often come across problems involving cracks and
will require at least a basic understanding of fracture
mechanics. Readers acquainted with the literature in
this field are likely to be familiar with the first edition
of Emmanuel Gdoutos’ introductory volume, which
appeared in 1993. This is, in turn, based on his earlier
book Fracture Mechanics Criteria and Applications, which
appeared in 1990. The second edition of Fracture
Mechanics, An Introduction was published in 2005 and
updates the earlier work by the introduction of new
chapters on composites, thin films, nanoindentation
and cementitious materials. Before examining the new
material, it is perhaps appropriate to summarise the
main part of the book which is essentially unchanged
from the first edition.
Gdoutos’ stated aim is to provide a comprehensive
introduction to the field of fracture mechanics with the
potential for use as a textbook for undergraduate and
postgraduate courses. He therefore addresses the funda-
mentals of the subject, starting with the linear elastic
case (LEFM), before extending this to elastic–plastic
materials and relating these approaches to the energy-
based perspective of Griffith. Later chapters address the
J-integral approach and mixed-mode cases, as well as
practical applications in the fields of dynamic fracture,
fatigue and micromechanics. An introductory chapter is
provided, which gives a historical view of the subject
and explains the motivation for characterisation of
cracks. Although the book starts from the level of basic
stress analysis, stress functions are introduced fairly early
on and this approach means that the book is probably
less accessible to today’s undergraduates than when the
material was first written. Postgraduate students, how-
ever should be able to handle the concepts required
without undue difficulty, although familiarity with ten-
sor notation is needed for some of the later chapters. In
contrast to the chapter on LEFM, the material on elastic–
plastic fracture is written at a more basic level and deals
essentially with the Irwin and Dugdale approaches.
Further coverage of plasticity is given later in the chapter
on the J-integral method.
The distinctive feature of the book, which sets it apart
from others in the field, is the provision of example
problems at the end of the majority of the chapters. These
will prove extremely useful, both for use on taught
courses and for the reader using the book independently.
Use of the examples will enable development of a com-
prehensive understanding of the material covered in each
chapter, although it should be pointed out that, aside
from a limited number of worked examples, answers to
the problems are not provided. Perhaps a web-based
resource could be created for these which would usefully
complement the written material.
Turning now to the additions in the second edition,
Gdoutos has added four short chapters on composite
materials, thin films, nanoindentation and cementitious
materials (i.e. concrete). The first three of these, in
particular, are important areas not often dealt with in
fracture mechanics textbooks. The chapter on composites
starts with a review of anisotropy, which is useful in its
own right, but less applicable to the micromechanics of
composite fracture than might first appear. The remain-
der of the chapter deals essentially with delamination,
mainly from an experimental perspective. In the thin-
film chapter, the case of a bi-material crack is examined,
and the Dundurs parameters are introduced to describe
material dissimilarity. The complex stress intensity factors
which occur in bi-materials are introduced, but there are
no references to later work (e.g. by Comninou) which
resolves the problem of the oscillatory singularity. Per-
haps because of the nature of the material, the new
chapters do not include example problems to match the
earlier part of the book.
In conclusion, the second edition provides a useful
update to a popular text book on fracture mechanics by
including some new material on important subjects of
topical interest. No significant changes have been made
to the earlier chapters. The book is recommended to those
seeking to develop a sound grasp of the principles of
fracture mechanics and of their application. It is parti-
cularly valuable, in my view, for the problems and worked
examples.
