Solutions for transversely isotropic piezoelectric infinite body, semi-infinite body and bimaterial infinite body subjected to uniform ring loading and charge

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 di}erent characteristic roots and multiple roots are all presented[ In the case of s0 s1 s2 s0based on the Green|s functions for semi!in_nite piezoelectric body and bimaterial in_nite piezoelectric bodythe Green|s functions for axisymmetric problems of semi!in_nite body and bimaterial in_nite body are obtained[ Taking PZT!3 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
