Abstract
A new constitutive model describing material response to cyclic loadin g is presented. The model includes dislocation densities as internal v ariables characterizing the microstructural state of the material. In the formulation of the constitutive equations, the dislocation density evolution resulting from interactions between dislocations in channel -like dislocation patterns is considered. The capabilities of the mode l are demonstrated for INCONEL 738 LC and Alloy 800H.
