Research Progress on Micromechanics of Domain Switching in Ferroelectric Materials

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.
