Abstract
- Dispersion equations of wave propagation in piezoelectric circular curved rods in an orthogonal curvilinear coordinate system are established in this paper, in which the displacements and electrical potential fields are described using Bessel functions. Characteristics of dispersion relations, distributions of displacements and electrical potential over the cross section are calculated. In the numerical examples, effects of various parameters on wave dispersions, distributions of displacement and electric potential of the first several modes over the cross section are investigated, in which influence of the changing of curvature radius of circular rods on distributions of displacement and electrical potential is compared, and also influence of whether considering the piezoelectric parameters in curved rods on dispersion is discussed.
