Abstract : Understanding the complexity of the fracture mechanics of brittle matrix composite: was a subject of several analytical studies in this work. The studies included finding the effect of imperfect fiber-matrix interfaces, both frictional and nonhomogeneous, on the fracture mechanics of composites; readdressing and questioning the current criteria for crack deflection at fiber-matrix interfaces used for developing optimum composite interfaces comparing axisymmetric and planar approximations of three dimensional fracture mechanic problems, since stiffness reduction and fracture toughness of composites are evaluated using such assumptions.
