CONSTITUTIVE EQUATIONS FOR DYNAMIC MATERIAL BEHAVIOR,

Abstract

The constitutive equations that have been developed for the dynamic behavior of materials presuppose the existence of a reference 'static' yield criterion. An alternative formulation motivated by the work on dislocation dynamics considers the total deformation to consist of elastic and plastic components throughout the deformation history. This procedure permits the consideration of large deformations (finite strains) in a direct manner. The present paper outlines an elastic-viscoplastic theory based on this approach and includes numerical results for an internally pressurized thick walled sphere. (Author)
