Abstract

This chapter introduces some fundamental concepts of plasticity that are used in Chapter 6 to formulate the concept of plastic hinge and in Chapter 7 to describe elasto-plastic models for frames; in the present one, only the uniaxial behavior of the material is considered. In this chapter, the key concepts of perfect plasticity, yield function, and plastic hardening are introduced. The two alternative formulations for plastic hardening, isotropic and kinematic, are discussed in detail. Plasticity is presented as a way to mathematically represent the experimental behavior of ductile materials; the limits of plasticity for describing reality are also established.
