The distributed element model, which had been proposed previously by the authors, was applied to the analysis of cyclic shear stress-shear strain behavior which changes with the number of cycles. In order to examine the applicability of the model, cyclic torsion tests were carried out under a constant shear strain amplitude. From the comparison of experiments with the theory, it appears that the model is suitable for describing the cyclic shear stress-shear strain behavior, and that the deformation behavior of materials under cyclic loading may be predicted reasonably well by the model. It is also shown that the cyclic hardening of materials can be explained based on the increase in the rate of hardening, H_t, and the distribution shift toward high yield strain with the number of cycles.
