Abstract
This paper presents two newly developed micromechanical models for the anal ysis of plain weave fabric composites. Both models utilize the representati ve volume cell approach. The representative unit volume of the woven lamina is divided into subcells of homogeneous material. Starting with the averag e strains in the representative volume cell and based on continuity require ments at the subcell interfaces, the strains and stresses in the composite fiber yarns and matrix are determined as well as the average stresses in th e lamina. Equivalent homogenized material properties are also determined. I n their formulation the developed micromechanical models take into consider ation all components of the three-dimensional strain and stress tensors. Th e performance of both models is assessed through comparison with available results from other numerical, analytical, and experimental approaches for c omposite laminae homogenization. The very good accuracy together with the s implicity of formulation makes these models attractive for the finite eleme nt analysis of composite laminates.
