英文摘要	Effect of interface stress upon the interaction between a screw dislocation and a coated nanoinhomogeneity is investigated in the framework of surface elasticity. By using the complex variable function method, the stress fields in the inhomogeneous materials and the image force acting on the screw dislocation are derived analytically. The results indicate that, when the radius of the coated inhomogeneity is reduced to nanometers, the influence of interface stress on the motion of the dislocation near the inhomogeneity becomes significant and the image force acting on the screw dislocation depends on the coated inhomogeneity size, which differs from the classical solution.
