中文摘要：

This review presents the progress and current status of the inves-tigation on electromechanical deformation and fracture of piezoelectric/ferroelectricmaterials. An attempt is made to summarize a few fundamental aspects, which in-clude electromechanical constitutive relations, piezoelectric micromechanics and elec-tric fracture and fatigue, instead of describing all technological backgrounds, basicphysics, experimental findings, and theoretical developments. A number of open ques-tions and future prospective are presented. It is hoped that this review will encouragepeople to join the exploration of this important and interesting field.
