A review is given of one approach to the formulation of equations for elastic-plastic solids at finite strains which lends itself to numerical analysis. A generalization of J2 flow theory to large strains is given which is in a form convenient for applications. Several aspects of the analysis of necking in tension are discussed from this point of view. Applications of the formulation to nonlinear plate and shell theory are also discussed. Author
