The modeling of mechanical properties of materials and structures is a complex and wide-ranging subject. In some applications, it is sufficient to assume that the material remains elastic, i.e. that the deformation process is fully reversible and the stress is a unique function of strain. However, such a simplified assumption is appropriate only within a limited range, and in general must be replaced by a more realistic approach that takes into account the inelastic processes such as plastic yielding or cracking.
This book presents a comprehensive treatment of the most important areas of plasticity and of time-dependent inelastic behavior (viscoplasticity of metals, and creep and shrinkage of concrete). It covers structural aspects such as:

incremental analysis
limit analysis
shakedown analysis
optimal design
beam structures subjected to bending and torsion
yield line theory of plates
slip line theory
size effect in structures
creep and shrinkage effects in concrete structures.

The following aspects of the advanced material modeling are presented:

yield surfaces for metals and plastic-frictional materials
hardening and softening
stress-return algorithms
large-strain formulations
thermodynamic framework
microplane models
localization of plastic strain.

Inelastic Analysis of Structures is a textbook for basic and advanced courses on plasticity, with a slight emphasis on structural engineering applications, but with a wealth of material for geotechnical, mechanical, aerospace, naval, petroleum and nuclear engineers. The text is constructed in a very didactical way, while the mathematics has been kept rigorous.
