What is Anti-plane interfacial Yoffe-crack between a piezoelectric and two orthotropic layers about?

This paper provides the problem of an interfacial crack moving along the interface between a piezoelectric and two orthotropic materials under electromechanical longitudinal shear loadings. Fourier transforms are used to reduce the problem to the solution of a pair of dual integral equations, which are then reduced to a Fredholm integral equation of the second kind. The dynamic field intensity factors are determined in terms of a Fredholm integral equation of the second kind. To show the geometrical and electromechanical effects on the dynamic stress intensity factor for various material combinations, some numerical examples are presented. The numerical results show that the dynamic stress intensity factor depends on the crack length, the ratios of stiffness and thickness, and the magnitude and direction of electrical loads as well as crack speed.
