A stress-based model of the ÿnite element method is evolved for two-dimensional quasi-static plasticity problems. The self-equilibrating ÿelds of stresses are constructed by means of the Airy stress function, which is approximated by three types of elements: the Bogner-Fox-Schmit rectangle, the Hsie
## Abstract In this paper two plane strain quadrilateral elements with two and four variables, are proposed. These elements are applied to the analysis of finite strain elasto‐plastic problems. The elements are based on the enhanced strain and B‐bar methodologies and possess a stabilizing term. The
