%X The field equations for three-dimensional problems in transversely isotropicpiezoelectric medium may be reduced to four second order linear partial differential equa-tions,in which the elastic displacement components and electric potential functions areunknowns.In this paper,expressions for displacement components and electric potentialfunctions are derived by using four harmonic functions,they form the so-called general solu-tions of the field equations for three-dimensional problems.As an example,a penny...
