(PZT) piezoelectric vibrators was investigated by admittance circles. The resonant frequency coud be drawn by admittance circles
and then the elastic constant
as a token of elastic fatigue
could be calculated. The result indicated that the elastic fatigue appeared when PZT work in the resonant frequency and the telescopic vibration times were over 10
