The problem involving the interaction effects between a wedge disclination dipole and an elastic circular inclusion was investigated. Utilizing the Muskhelishvili complex variable method, the closed form solutions were derived for complex potentials and stress fields due to a wedge disclination dipole located near the circular inclusion. The strain energy and the force acting on the disclination dipole center were also calculated. The influence of the orientation and the location of the disclination dipole as well as the material elastic dissimilarity upon the equilibrium position of the disclination dipole was analysed in detail. The results showed that, for certain combinations of material constants, the disclination dipole had a stable equilibrium point near to the inclusion. Also, the forceon the disclination dipole was very much affected by the orientation of the disclination dipole. The present solutions subsumed previously known results as special cases.
