| Abstract: | This Paper research on coupling field for antiplane strain problerns of the circular- arc electrically permeable slit cracks between bonded dissimilar piedectric materials under the concentrated forces by using analysis continuation principle of functions of complex variable. Soutions in closed-form of the complex potentials and the field intensity factors are given for a single circular-arc crack. It is shown from the solutions that the coupled field has (1/2) type of singularity at the crack tip |
