title = "Fatigue crack propagation in three-point bending of piezoceramics under electromechanical loading",
abstract = "In this study, we present a combined numerical and experimental examination of the fatigue crack propagation in piezoelectric ceramics under electromechanical loading. A crack was created normal to the poling direction. Dynamic and static fatigue tests were conducted in three-point bending under electric fields using single-edge precracked-beam method. A nonlinear finite element analysis was also performed to evaluate the energy release rate for the permeable, impermeable and open crack models, and the effects of electric field and polarization switching on the energy release rate were discussed. The results were then examined in terms of the crack propagation velocity and lifetime vs energy release rate curves.",
