Analysis of Fracture Data of Conductive Cracks in Lead Zirconate Titanate PIC 151 Ceramics with the Charge-free Zone Model

The charge-free zone model for electrically conductive cracks in
piezoelectric ceramics is reviewed and applied to interpret the experimental
results on poled lead zirconate titanate PIC 151 ceramics. Good agreement
between the experimental results and the charge-free zone model indicates again
that the concepts of fracture mechanics can be applied to the failure of conductive
cracks in piezoelectric ceramics.
