Paper Abstract
The free vibrations of a solid 3D piezoelectric cylinder of class 6 mm are investigated. First the equations of motion are reformulated with the help of three scalar potentials. This decouples the SH waves and is done in a way which is coordinate-free in the transverse coordinates. Next the modes in an infinite plate are derived in cylindrical coordinates, and this involves Bessel functions in the radial direction. A superposition of these modes is then used to form the eigenmodes of the cylinder with a finite radius. The remaining lateral boundary conditions give a determinantal condition for the eigenfrequencies. Numerical results are given and are compared with previous published results.
