This research presented an analytical study of the interaction problem of an edge dislocation with a circular inclusion with a circumferentially inhomogeneously imperfect interface. The interface, which was modeled as a spring (interphase) layer with vanishing thickness, was characterized by that in which there was a displacement jump across the interface in the same direction as the corresponding tractions, and the same degree of imperfection was realized in both the normal and tangential directions. Furthermore, the interface parameter was non-uniform along the interface. In order to arrive at an elementary form solution, a conformal mapping function was introduced. Then the stress field as well as the Peach–Koehler force acting on the edge dislocation could be obtained from the derived complex potentials. Calculations demonstrated that the non-uniform interface parameter had a significant influence upon the stress field.
