Inelastic Analysis of Structures

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.
