The subject of computational plasticity encapsulates the numerical
methods used for the finite element simulation of the behaviour of
a wide range of engineering materials considered to be plastic

i.e. those that undergo a permanent change of shape in
response to an applied force. Computational Methods for
Plasticity: Theory and Applications describes the theory of the
associated numerical methods for the simulation of a wide range of
plastic engineering materials; from the simplest infinitesimal
plasticity theory to more complex damage mechanics and finite
strain crystal plasticity models. It is split into three parts -
basic concepts, small strains and large strains. Beginning with
elementary theory and progressing to advanced, complex theory and
computer implementation, it is suitable for use at both
introductory and advanced levels. The book:
Offers a self-contained text that allows the reader to learn
computational plasticity theory and its implementation from one
volume.
Includes many numerical examples that illustrate the
application of the methodologies described.
Provides introductory material on related disciplines and
procedures such as tensor analysis, continuum mechanics and finite
elements for non-linear solid mechanics.
Is accompanied by purpose-developed finite element software
that illustrates many of the techniques discussed in the text,
downloadable from the book's companion website.

This comprehensive text will appeal to postgraduate and graduate
students of civil, mechanical, aerospace and materials engineering
as well as applied mathematics and courses with computational
mechanics components. It will also be of interest to research
engineers, scientists and software developers working in the field
of computational solid mechanics.
