Abstract
AbstractOn the basis of the linear magnetoelectroelasticity, the interaction problem between a generalized screw dislocation and a fibrous three-phase magnetoelectroelastic composite penetrated by a semi-infinite wedge crack is investigated in this paper. The fibrous magnetoelectroelastic composite is composed of three dissimilar materials bonded along two concentric circular interfaces. The magnetoelectroelastic materials are assumed to be transversely isotropic and have the same poling direction. The analytical derivations are based on the complex variable, conformal mapping, analytical continuation and image singularity methods. Numerical calculations are given graphically for studying the effects of material combinations, geometric models, wedge angles and the load type on the generalized stress fields, the generalized stress intensity factors, and the forces on the dislocation.
