Abstract

Abstract

Exact solutions in form of elementary functions were derived for the stress and electric displacement intensity factors of a circular crack in a transversely isotropic piezoelectric space interacting with various stress and charge sources:force dipoles,electric dipoles,moments,force dilatation and rotation.The circular crack includes penny-shaped crack and external circular crack and the locations and orientations of these resultant sources with respect to the crack are arbitrary.Such stress and charge sources may model defects like vacancies,foreign particles,and dislocations.Numerical results are presented at last.
