| Abstract: | By virtue of foundation solutions of field intensity factors obtained by Hou\ \{\\}, exact solutions in elementary functions are derived for the stress and electric displacement intensity factors of an external circular crack in a transversely isotropic piezoelectric body interacting with various stress and charge sources: force dipoles and electric dipoles. Locations and orientations of the stress and charge sources with respect to the crack are arbitrary. |
