Краткое описание

Effective medium approximations are developed to estimate the effective conductivity of unidirectional composites that are composed of coated fiber-inclusions embedded in a continuous matrix phase. The two-phase coated inclusions are substituted by equivalent one-phase inclusions from a dilute solution. Then, usual effective medium approximation schemes are applied to the equivalent medium to estimate the conductivity of original three-phase composites. Applications with numerical and experimental illustrations are given for certain periodic and random composites.
