Paper Abstract

A soft PZT was subjected to cyclic loading at its resonance frequency. Both the piezoelectric coefficient, d31, and the transverse coupling coefficient, k31, decreased in a manner consistent with 90 degrees and 180 degrees domain reorientation, with the greatest decrease coinciding with the largest stress and temperature. In contrast, for high loads and temperatures, the elastic compliance, S11E, and the dielectric constant, K33 decreased in a manner consistent with increased, rather than decreased, alignment of the c-axes.
