In this study, singular fields at the ends of fibers are discussed by the use of models of rectangular and cylindrical inclusions in a semi-infinite body under pull-out force. The body force method is used to formulate those problems as a system of singular integral equations where the unknown functions are densities of the body forces distributed in a semi-infinite body having the same elastic constants as those of the matrix and inclusions. Then, generalized stress intensity factors at the corner of rectangular and cylindrical inclusions are systematically calculated with varying the elastic modulus ratio and aspect ratio of inclusions. The effects of elastic modulus ratio and aspect ratio of inclusion upon the stress intensity factors are discussed.
