| Abstract: | Based on the reciprocity theorem of piezoelectric media and the solution 1] of a penny-shaped crack in a transversely isotropic piezoelectric body subjected to the symmetric point charges and normal point forces, the expression of opening displacement of a penny-shaped crack in a transversely isotropic piezoelectric body subjected to the arbitarily located point forces and point charges were obtained in terms of elementary functions. At last, graphics are shown for PZT-4 and the corresponding non-piezoelectric materials. |
