While the displacement components and electric potential functions are the essential unknowns,the governing equations of three-dimensional problems in transversely isotropic piezoelectric media arecomposed of four second order linear partial differential equations obtained with the aid of four har-monic functions which are used to express the components of displacements and the electric potentialfunctions.As an application of the general solution,the penny-shaped crack problems in piezoelectricceramic materials under venture action by tension and bending loads are solved and the analytic ex-pressions of stresses and electric displacement near the crack top are gotten. The results demonstratethat the crack top field and force intensity and electric displacement intensity all appear the complicat-ed coupling effects that take place between electric fields and mechanical deformation.
