Abstract

We investigates the fatigue behavior of cracked piezoelectric ceramics in cyclic bending under electric fields both theoretically and experimentally. Fatigue tests were carried out in three-point bending with the single-edge precracked-beam (SEPB) specimens. The crack was created normal to the poling direction. Number of cycles to failure was measured under electric fields. Plane strain finite element analysis was also performed, and the effect of polarization switching on the energy release rate was discussed under high negative electric field. In addition, mechanisms for crack growth were discussed by scanning electron microscope examination of the fracture surface of the piezoelectric ceramics.
