The aim of this paper is to provide modeling and numerical analysis of delamination for increasingly complex woven reinforced composite materials. Modeling of the woven reinforced composite materials due to the existence of the weft and woof filaments of fibers was a significant part of this research. The Finite Element (FEM) model of the unit-cell, which is a small element of the composite which describes all of the mechanical properties of the material, provided the required results of the strain energy with a low volume of computation. The computed loads by FEM were put in derived equations of fracture mechanics. The criterion of strain energy release rate (Gc) have been used. The obtained numerical results showed the growth of delamination along the weft filaments and a sudden change in the point of crossing of the woof filaments. The curves drawn by finite element method showed that the best answer would be given by usage of singular elements for modeling of crack tip comparing by usage brick elements. So results of modeling by singular elements were developed in this paper. Numerical results were in good correlation with the experimental results and the difference was less than 10%
