Abstract
Detailed expressions are derived in closed-form for the field components at a general point in the deformation of magnetoelectroelastic media by a stack of parallel, antiplane shear cracks to which non-uniform mechanical, electric, and magnetic loads are applied, by exploiting a generalized technique of continuous distributions of dislocations. Their angular variations around a crack tip are deduced; from which comprehensive, novel representations for the appropriate stress, electric displacement, and magnetic induction intensity factors follow. Representative numerical results are illustrated graphically. The phenomenon of the so-called crack shielding effect is exhibited. Limiting special cases are considered as validation of this analysis.
