LAYERED PIEZOELECTRIC MEDIUM WITH INTERFACE CRACK UNDER ANTIPLANE SHEAR

The theory of linear piezoelectricity is applied to solve the anti-pla ne shear problem of a piezoelectric layer sandwiched by two dissimilar homogeneous materials with a crack at the interface. Both mechanical and electrical loads are applied to the piezoelectric laminate. By the use of Fourier transforms, the mixed boundary value problem is reduce d to a singular integral equation which is solved numerically to deter mine the stress intensity factors for several layered piezoelectric me dia, and the results are presented in graphical form.
