ABSTRACT
In this chapter, for easy understanding of elastoplasticity, the fundamentals of elastoplasticity—that is, yield stress (function), hardening function, and loading condition—are first explained in one-dimensional (1D) conditions because the formulation is given using one stress (σ) and one strain (ε). In addition to these fundamentals in 1D elastoplasticity, the other requirements in multidimensional plasticity (i.e., coaxiality and flow rule) are explained. Then, the formulation of conventional elastoplastic models is described.
