title = "Evaluation of electric fracture properties of piezoelectric ceramics using finite element and double torsion test techniques",
abstract = "This paper presents the results of an experimental and numerical investigation in electric fracture behavior of composite PZT double torsion (DT) specimens. DT tests were conducted on a commercial piezoelectric ceramic bonded between two metals. Fracture loads under different electric fields were obtained from the experiment. Nonlinear three-dimensional finite element analysis was also employed to calculate the energy release rate for DT specimens based on the exact (permeable) and approximate (impermeable) crack models. The effects of applied electric field and domain switching on the energy release rate are discussed, and the model predictions are compared with the results of the experiments.",
