Abstract: The magnetoelectroelastic interaction of a generalized screw dislocation with circular interfacial rigid conducting line inclusions is dealt with.By using Riemann-Schwarz's symmetry principle integrated with the analysis of singularity of complex potentials,the general solution of the problem is presented.A closed form solution is derived when the interface contains one rigid line.With the application of perturbation technique,the perturbation stresses,electric displacement fields,magnetic induction fields are obtained.The image force acting on the generalized screw dislocation is calculated using the generalized Peach-Koehler formula.The influence of interfacial rigid line geometry and material mismatch on the image force is discussed.The solutions can be used as Green's functions to obtain the corresponding solutions for the case of arbitrary distribution dislocations and solve the problem of the interaction between interfacial rigid lines and arbitrary shape crack under antiplane mechanical,in-plane electric and magnetic loadings at infinity.
