Dynamic fundamental solutions for transversely isotropic piezoelectric materials of crystal class 6 mm

In the present work, a fundamental solution for transient 3D dynamic piezoe lectricity is derived. The theoretical basics are reviewed with special att ention to the case of transversely isotropic piezoelectric materials of the crystal class 6 mm. Numerical results concerning both convex and non-conve x slowness surfaces are presented, where different singularities, present o nly in anisotropic materials, are analysed.
