✦ Synopsis

Based on the `average stress in the matrix' concept of Mori and Tanaka (Mori, T., Tanaka, K., 1973. Average stress in matrix and average elastic energy of materials with mis®tting inclusion. Acta Metall. 21, 571±580) a micromechanical model is presented for the prediction of the elastic ®elds in coated inclusion composites with imperfect interfaces. The solutions of the eective elastic moduli for this kind of composite are also obtained. In two kinds of composites with coated particulates and ®bers, respectively, the interface imperfections are taken to the assumption that the interface displacement discontinues are linearly related to interface tractions like a spring layer of vanishing thickness. The resulting eective shear modulus for each material and the stress ®elds in the composite are presented under a transverse shear loading situation.
