摘要
In the spirit of the Griffith's theory on mechanical fracture, a fracture criterion of ferroelectric ceramics in terms of energy analysis is proposed in this paper. The energy criterion is compared with the local energy release rate proposed by Gao et al. and the strain energy release rate of Park and Sun. In addition, the criterion can be used to explain why a positive electric field promotes cracking while a negative electric field can retard crack propagation.
