摘要

摘要: 铁电材料最显著的显微组织特征是电畴结构，其自发极化矢量可以随外加电/力场转动（即畴变），从而使铁电材料具有独特的机电性能。从畴变理论出发，综述了畴变准则的研究进展，并介绍了畴壁动力学以及与畴变相关的断裂力学研究成果，旨在为铁电材料的细观力学研究提供参考。

Abstract: Domain structure is deemed as the remarkable microstructural feature of ferroelectric materials, and its spontaneous polarization vector can be switched by the external applied electric/mechanical field (namely domain switching), leading to multiply electromechanical properties of ferroelectric materials. Starting from the theory of domain switching, research progress on the domain switching criterion is reviewed, and research results of the domain-wall dynamics and the domain switching-dependent fracture mechanics are described. It is aimed at providing some references for the micromechanics research of ferroelectric materials.
