Abstract
Abstract The constitutive model due to Bodner and Partom is compared with the authors' theory in which the state, or structure parameter is associated with the total dislocation density. The evolution equation for this state parameter includes such microstructural features as the effect of small grain size or the presence of second-phase particles. Using the similarity of the two models, an extension of the Bodner-Partom formulation to take account of these features, as well as of the experimental observation that the strain hardening rate is strain rate dependent, is proposed. On the other side, guided by the Bodner-Partom model, a generalization of the authors' model to the case of multiaxial deformation is given.
