Abstract
Woven composite materials are made of epoxy layers reinforced by textile, and thin epoxy layers that bond the reinforced layers. In the present paper, the composites are modeled by an isotropic epoxy layer and two reinforced elastic half-planes that have anisotropic elasticity. A crack is situated in the layer parallel to the interfaces, and stress intensity factors are solved under normal tensile stress applied perpendicular to the crack. Fourier transformations are utilized to reduce the boundary conditions with respect to the crack to two pairs of dual integral equations. To solve the equations, the differences in crack surface displacements are expanded to a series of functions that are zero outside the crack. The unknown coefficients in the series are solved by the Schmidt method so as to satisfy the conditions inside the crack. Numerical calculations are carried out for some crack configurations.
