The book is available in PDF format, and can be downloaded for free from various online sources. The updated version of the book includes new chapters on non-linear elasticity, plasticity with damage, and multi-scale modeling.
The theory of plasticity deals with the behavior of solids that are subjected to external loads, and undergo permanent deformation. The theory is based on the concept of yield stress, which is the stress at which a material begins to deform plastically. The book is available in PDF format, and
