The effects of interaction between crack-like defects in fiber reinforced composite materials on the local stress concentrations in their neighbourhoods are theoretically investigated from the macro and micromechanical points of view. The most simple models consisting of homogeneous and heterogeneous anisotropic elastic plates with two colinear or parallel cracks are used. Plane stress and plane strain conditions are assumed, and the mathematical formulations are made in terms of the Cauchy-type singular integral equations of the first kind through the methods of harmonic-type stress functions and Fourier transforms. Numerical calculations are carried out for the stress intensity factors, and the results thus obtained from these models are campared to each other.
