INTENSITY FACTORS OF ELECTRICALLY PERMEABLE INTERFACIAL CRACKS OF ANTIPLANE STRAIN PROBLEMS IN BONDED DISSIMILAR PIEZOELECTRIC MATERIALS

Coupling field for antiplane strain problems of the electrically permeable slit cracks between bonded dissimilar piezoelectric materials under concentrated loads is studied using complex function method. Solutions of the complex potentials in closed-form and the field intensity factors are given for a single crack. It is found that the order of singularity at the crack tip in the coupled field is (1/2).
