Description

Introduction to Engineering Plasticity covers the mathematical theories of plasticity that are based on hypotheses and assumptions to represent the experimental observations as generalized mathematical formulations. Following a brief introduction in the first chapter, the next three chapters of the book deal with stress and strain tensors, and stress-strain relationships followed by yield criteria and their experimental verifications in chapter five. Associated flow rules and plastic stress-strain relationships are also derived in this chapter. Chapters six and seven present the concepts of plastic anisotropy and plastic instability. The slip-line field theory as applied to plane strain problems of rigid, perfectly plastic materials is presented in chapter eight and the limit theorem is elaborated in chapter nine.
