摘要：

A two-dimensional electroelastic analysis is performed on a transversely isotropic piezoelectric material containing defects. A general solution is provided in terms of complex potentials, with emphasis being placed on stress concentrations that arise in the vicinity of circular and elliptical holes. It is shown that for this genre of problem both mechanical and electrical variables are responsible for the peak stresses.
