Abstract
The problem of a penny-shaped crack in a transversely isotropic piezoelectr ic material loaded by both normal and tangential tractions and by electric charges is analyzed. Closed-form solutions are obtained for the full electr oelastic fields as well as for the stress and electric displacement intensi ty factors. Solutions are also obtained for the (non-trivial) limiting case of a half-plane crack. The results are illustrated on the example of piezo ceramics PZT-6B.
