In this work the effective properties of materials containing coated inclusions are analyzed. The analysis is based on a double-homogenization realized with the aid of Hill’s interfacial operators, Eshelby’s solution for ellipsoidal inclusion, and the Mori-Tanaka scheme. The system inclusion-coating is assumed to consist of two confocal spheroids. The proposed approach gives closed-form solutions and holds for both thin and thick coatings.
