Newly engineered high-performance composite materials are very often reinforced by particles, continuous or short fibers and thin layers. Cracks encountered in such materials are more often than not effected by its tip being located in one particular small particle or thin layer of a composite. The physical effect of such apparently small geometric alternations on the toughness of the material is finite and must be carefully examined. Fatigue crack propagation usually leads to the formation of a thin layer of damaged material surrounding the propagating crack. The thin layer of damage, however, is known to have finite effects on the various generalized Eshelby forces that drive the damage. The interaction of a crack and a small inhomogeneity in an otherwise homogeneous medium is studied in this thesis. Asymptotically deduced computer codes are developed for the purpose of computing any and all physical quantities relevant to the aforementioned problems.Subjects--Topical Terms:
