Research Abstract

Small crack growth behavior in poled lead zirconate titanate was investigated under cyclic electric loadings. The crack located at partial electrode edge grew along the boundary of electrode during the loading. The crack growth rate decreased with increasing crack length and non-propagating crack was reached. The growth rate and crack length of non-propagating crack were affected by amplitude of the electric loadings and environmental temperature and humidity.
