This paper is an effort to first modify two cyclic plasticity models developed for homogeneous metals to address the heterogeneous nature of particulate metal matrix composites (PMMCs), and subsequently to evaluate the resulting relations both theoretically and experimentally. Specifically, using the original Mro´z model and the endochronic theory of plasticity as their bases, two sets of elastic-plastic constitutive relations are identified. These sets of relations account for the interaction in stress fields between adjacent particles in PMMCs. The behavior predicted by each model is compared with experimental results obtained from a series of uniaxial and biaxial (tension-torsion) tests performed on circular specimens made of the 6061/Al2O3/20p-T6 PMMCs with 20% volume fraction of particles. The materials are tested for a variety of applied monotonic and cyclic loading paths.
