| Abstract: | We analyze anti-plane vibrations of a circular cylindrical elastic shell electrically driven by a piezoelectric actuator. The equations of linear elasticity and linear piezoelectricity are used. The mathematical problem is solved using trigonometric series. Basic vibration characteristics including resonant frequencies, mode shapes and electric admittance are calculated. |
