A PHENOMENOLOGICAL MODEL FOR CYCLIC PLASTICITY

A phenomenological model is proposed for cyclic plasticity based on th e concept of distributed elements, which is capable of reflecting micr ostructural behavior of real materials under multiaxial cyclic loading conditions. By investigating the detailed behavior of the model, vari ous important phenomena and effects of materials in cyclic plasticity can be elucidated. Generalization of the model is also done to include cyclic hardening effects. A thorough understanding of these complicat ed response mechanisms and material properties provides useful insight and guidelines for validating analytical models and for performing ex perimental studies in the related areas of cyclic plasticity.
