Abstract
An algorithm for finite element analysis of problems in elastoplastici ty with continuous stress and strain approximation is presented. By a global iteration procedure, equilibrium is preserved at the nodes in a weak sense, and the local constitutive relation between stresses and strains is satisfied. A high order numerical integration is used to ac hieve a good quality stiffness matrix and to evaluate the boundary bet ween elastic and plastic regions in the case of partly plastic element s.
