Solutions to a piezoelectric half-plane with a fixed conductorsurface electrode subjected to two generalized singularities (linedislocation and/or lien force and free charge) are presented.Coublomb forces acting on the singularities due to the boundarypolarization changes of medium and the induction charg- es ofconductor electrode are analyzed in detail. The interaction betweenthe two singularities is also analyzed numerically. Results show thatCoulomb forces will become important as the free change approachesthe boundary or two singularities move closely.
