English abstract:
A replacement scheme is explored which uses perfectly bonded ellipsoidal replacement inhomogeneities to model the thermal conduction behavior of non-ellipsoidal fiberlike inhomogeneities with imperfect interfaces. Replacement conductivity and dilute gradient concentration tensors are introduced and their numerical evaluation from singleinhomogeneity models is discussed. The replacement tensors are incorporated into orientation averaged and multiinclusion Mori-Tanaka schemes to study the thermal conduction responses of composites reinforced by randomly oriented short fibers at non-dilute volume fractions. Results on the effective conductivities and the local fields in individual fibers are compared to predictions from numerical homogenization of unit cells containing periodic arrangements of randomly oriented short fibers in a matrix.
