The problem of propagation of acoustic waves in an infinitely long piezoelectric cylinder of circular cross-section has been studied. The material of cylinder was considered transversely isotropic (axially symmetric). However, propagating waves may be not axisymmetric, for example, the flexural wave modes. We give mathematical formulation of the problem, description of a numerical solution method, and the results of calculations of the phase velocity and electromechanical coupling coefficient for the waves in the cylinder of piezoelectric ceramics such as PZT 24.
