Abstract

In this study, we report theoretical and experimental examination of the fracture and fatigue behavior in cracked piezoelectric PZT ceramics under electric fields. Delayed fracture and dynamic fatigue tests were carried out in three-point bending with the single-edge precracked-beam specimens. The crack was created normal to the poling direction. Time-to-failure and fracture load under DC/ AC electric fields were obtained from the experiment. Finite element computation was also carried out, and the energy release rate of cracked PZT specimens under DC/AC electric fields was calculated. The results were then discussed in terms of the energy release rate versus lifetime curve. In addition, the effect of electric fields on the critical energy release rate was examined.
