A stress-based model of the รฟnite element method is evolved for two-dimensional quasi-static plasticity problems. The self-equilibrating รฟelds 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
