Substituting Eq. (39) into Eqs. (7), (9), the generalized stress and strain field of inhomogeneity when the dislocation located in inhomogeneity can be obtained.

This work is devoted to investigate the magnetoelectroelastic interaction between a generalized screw dislocation and an elliptic inhomogeneity containing a confocal crack in piezoelectric/piezomagnetic composite subjected to remote anti-plane shear stress field, in-plane electric and magnetic field. By using the complex variable method of elasticity, the closed-form expressions of complex potentials of matrix and inhomogeneity are obtained for the dislocation locating both in matrix and inhomogeneity. The expressions of the generalized stress/...
