Effective elastic moduli of particulate composite materials with imperfect interfaces

The effect of imperfect interfaces on the elastic moduli of particulate composite materials is studied. The interfaces are assumed to belong to a linear spring type. The average stress and strain in the inhomogeneity is obtained by using the elastic solution of a single inhomogeneity with imperfect interface. Taking into consideration for the interaction of the inhomogeneities in the composite, we use differential methods, self-consistent method and Mori-Tanaka method to obtain the effective moduli of the composite. A comparison of these methods under imperfect interface condition is given out at the end of this paper.
