Abstract
In this study, singular stress 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
ratio, length, and spacing of the location from edge to inner of the body. The effects of elastic modulus
ratio and aspect ratio of inclusion upon the stress intensity factors are discussed.
