Dislocation emission mechanisms for micro crack initiation are proposed, at the tips of a semi-infinite rigid conducting line for plane case and a finite rigid conducting line for plane and antiplane cases in a piezoelectric medium. The crack is simulated by distributed piezoelectric screw/edge disl...
