Abstract

A finite element method for finite inelastic strain analysis of solids and structures is described. The method, which is based on a direct discretization of the equations of compatibility and angular momentum balance, represents a generalization of the mixed ‘stress function approach’ proposed for linear elasticity by de Veubeke (1975). It captures the main advantages of hybrid-stress, direct stiffness, and reduced integration finite element methods while avoiding their principal drawbacks. Examples are included which demonstrate important features of the method.
