Abstract
Based on the fundamental solutions for transversely isotropic piezoelectric materials, the fundamental solutions of axisymmetric problems are derived by integration and explicit expressions for three possible cases of different characteristic roots and multiple roots are all presented. In the case of s 1 ≠ s 2 ≠ s 3 ≠ s 1, based on the Greens functions for semi-infinite piezoelectric body and bimaterial infinite piezoelectric body, the Greens functions for axisymmetric problems of semi-infinite body and bimaterial infinite body are obtained. Taking PZT-4 as an example, numerical computations are conducted by use of the fundamental solutions to axisymmetric problems. Comparison of the calculated results with those of FEM shows good agreement between them.
