Radially polarized cylindrical piezoceramic rings are studied experimentally. It is shown that the inphase resonance is characterized by very high amplitudes and electromechanical coupling coefficient. The distribution of internal stresses along the height differs from cosinusoidal in the middle part of the ring. The edge resonance is characterized by high stresses near the ends and is very weak in the middle part. The amplitude–frequency and admittance–frequency responses are plotted and discussed
