Antiplane problem of periodic cracks in piezoelectric medium

In this article, the generalized two-dimensional problem of periodic interfacial cracks, which under antiplane deformation and in-plane electric field in piezoelectric materials, is studied by means of the complex variable method of Muskhelishvili and Riemann–Schwarz theorem. In terms of the electrically impermeable boundary condition, the problem is reduced to a Riemann–Hilbert problem and then explicit closed-form solutions are obtained. Moreover, it can be found that the solution procedure in this article is very direct and concise.
