摘要：

A number of continuum mechanical models for the macroscopic and microscopic linear elastic behavior of composites reinforced by continuous, unidirectional, coaxially coated fibers are critically compared. For the study, the interphase is assumed to be of finite thickness and uniform. Selected analytical mean-field methods and Finite-Element-based periodic homogenization models are applied to obtaining predictions for the effective elastic tensors and moduli of generic composites of this type. In addition, the phase-averaged microscopic stresses are evaluated for some macroscopic load cases. By comparing these results modeling schemes capable of providing high-quality predictions are identified.
