Abstract
The low frequency applied voltage-displacement characteristics of PZT-4 and PZT-5H piezoelectric ceramics, in both disc and tubular form spectra obtained with a separation scanned Fabry-Perot interferometer. The operation of such interferometers, when used without servo-control, is discussed in relation to the results obtained. Creep, variation of strain constant with bias voltage and the effects of non-continuous cycling were also investigated.Keywords
