Mean-Field homogenization algorithms for materials involving two or more elastic-plastic constituent phases are investigated. The Voigt, Reuss and Self consistent schemes which are directly applicable to multi-phase systems are implemented. The shortcomings of these schemes are accuracy for the former two and computational efficiency for the latter. A new interpolative model is proposed which is aimed to be both computationally efficient and accurate. The results of the models are studied on the material point level for a prescribed uniaxial tensile deformation. It is observed that the response computed by the proposed scheme closely matches that computed by the Self Consistent approach.
