Sinossi
Plasticity for Structural Engineers is a practical work that provides engineers and students in structural engineering or structural mechanics with the background needed to make the transition from fundamental theory to computer implementation and engineering practice. It sets out initially to examine the stress-strain behaviors of materials under simple test conditions, goes on to show how these behaviors can be generalized under combined stresses, and finally outlines the finite element implementation of the generalized stress-strain relations for the solution of practical steel and concrete structural problems.Plasticity for Structural Engineers not only offers the reader an understanding of the fundamental principles and theory of plasticity in a form that does not require extensive mathematical experience, but also provides the reader with a compact and convenient summary of the modern development of concrete plasticity and limit analysis in structural engineering.
