Boundary integrate equation method for semi-permeable vertical planar cracks in 3D piezoelectric media

In this paper, the boundary integral equation method is developed to study a vertical planar crack under the electrically semi-permeable boundary condition. The crack face is parallel to the poling direction and normal to the plane of isotropy in three-dimensional (3D) transversely isotropic piezoelectric media. The result shows that the singularity order is still the ordinary r ^{Read more}
