This present paper describes a micro/macro mechanical study of the elastic-viscoplastic behavior of unidirectional metal matrix composites (MMC). The micromechanical analysis of the elastic moduli are based on the Composite Cylinder Assemblage model (CCA) with comparisons also drawn with an Representative Unit Cell (RUC) technique. These `homogenization' techniques are later incorporated into the Vanishing Fiber Diameter (VFD) model and a new model is proposed. The finite element method is employed as the principal analysis in conjunction with the Bodner and Partom thermoviscoplastic constitutive model for the associated macroscopic analysis. The formulations developed are compared against experimental and analytical results available in the literature.
