| مستخلص: | The charge-free zone model proposed by Zhang et al. for the failure of conductive cracks in dielectrics was extended to predict the failure behavior of conductive cracks in piezoelectric ceramics. Piezoelectric ceramics were treated as mechanically brittle and electrically ductile materials in the charge-free zone model. The failure criterion, developed from the charge-free zone model, for conductive cracks in piezoelectric ceramics under mechanical and/or electrical loading has ail elliptic shape in terms of the normalized electric intensity factor and the normalized stress intensity factor. The experimental results reported in Part II of the series verified the theoretical predictions. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. |
