Electromechanical deformation and fracture of piezoelectric/ferroelectric materials

This review presents the progress and current status of the investigation o n electromechanical deformation and fracture of piezo electric/ferroelectri c materials. An attempt is made to summarize a few fundamental aspects, whi ch include electromechanical constitutive relations, piezoelectric micromec hanics and electric fracture and fatigue, instead of describing all technol ogical backgrounds, basic physics, experimental findings, and theoretical d evelopments. A number of open questions and future prospective are presente d. It is hoped that this review will encourage people to join the explorati on of this important and interesting field.
