Abstract�� Several representative micro-mechanical models for the analysis of the effective elastic properties of unidirectional fiber-reinforced composites and textile composites are briefly reviewed, and their characteristics are pointed out. In view of the limitations of the classical mechanical models for the prediction of the overall elastic behaviors of textile composites, a more generalized method is established. According to the fact that the in-plane components of strain tensor and the out-of-plane components of stress tensor are continuous across a perfect interface, interactions between phases are considered, and the perfect interface based formulas for homogenization are derived. This method has been applied to determine the effective elastic modulus of a unidirectional fiber-reinforced composite, and satisfactory results are obtained.
Keywords�� composite materials   elasticity   homogenizing   mechanical model   textile   perfect interface
