Paper Title:
Electrically Nonlinear Fracture Analysis of Piezoelectric Materials Based on CED (Crack Energy Density)
  Abstract

An electrical nonlinear constitutive model for piezoelectric material is studied in this paper. Electric yielding criterion and yielding effect on CED are investigated. Using the mechanical part of CED as a fracture parameter, it is shown that the predicted fracture loads through FEA for compact tension specimen is in accordance with corresponding experimental results.
