This study proposes an integrated numerical model to estimate the mechanical behavior of adhesively bonded joints consisting of different 2-D plain woven textile composites. To predict the elastic constants of 2-D plain weaves, a hierarchical modeling is introduced. In the fracture mechanics of adhesively bonded joints, the cohesive zone modeling is applied to a system of anisotropic/isotropic elastic material in the composite adherence. From fulfilling numerical analyses and experimental tests
more » ... of composite bonded joints, the effects of geometrical yarn shapes on the fracture mechanics are surveyed. Through result comparisons between the numerical analyses and the experimental tests, the validation of present model is examined.
