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.
