Aim To investigate the anti-plane problem of crack centers that lie in rectangular vertices and show doubly periodical distribution in infinite and uniform piezoelectric composite materials. Methods Conformal mapping and elliptical function are used to investigate the anti-plane problem. Results/Conclusion The closed-form solution of the anti-plane problem of crack centers that lie in rectangular vertices and show doubly periodical distribution in piezoelectric composite materials is put forward. In the meantime, stress intensity factor and electric displacement intensity factor are obtained.
