We develop a rigorous solution to the antiplane problem of a circular inhomogeneity embedded within an infinite isotropic elastic medium (matrix) under the assumption of nonuniform remote loading. The bonding at the inhomogeneity/matrix interface is assumed to be homogeneously imperfect. We examine both the case of a single circular inhomogeneity and the more general case of a three-phase circular inhomogeneity. General expressions for the corresponding complex potentials are derived explicitly in both the inhomogeneity and in the surrounding matrix. The analysis is based on complex variable methods. The solutions obtained demonstrate the effect of the prescribed nonuniform remote loading on the stress field within the inhomogeneity. Specific solutions are derived in closed form which are verified by comparison with existing solutions.
