The torsional vibration of a piezoelectric solid cylinder of arbitrary cross section of (622) class
The torsional vibration of a piezoelectric solid cylinder of arbitrary cross-section of class (622) crystals is investigated. The boundary conditions are satisfied using the Fourier expansion collocation method, and the frequency equation which is applicable for the general cross- section is derived. Numerical calculations have been carried out for the circular cylinder and elliptic cylinders of \(\beta\)-quartz. The frequencies obtained in the present method for the circular cylinder are compared with those of an exact method.
