Preisach Modeling of Electric-Field-Induced Strain of Ferroelectric Material Considering 90° Domain Switching

Abstract

Preisach modeling of a field-induced nonlinear strain of a ferroelectric material was carried out. A hysteron having a tristable property was proposed. The three stable states correspond to the three stable polarization states of a ferroelectric material. The domain evolution under an electric field was calculated. Finally, the electric-field-induced strain of ferroelectric ceramics was calculated and compared with experimental values. The proposed model enables the description of major and minor strain butterfly loops of ferroelectric materials.

Three-Dimensional Phase Field Simulations of Hysteresis and Butterfly Loops by the Finite Volume Method

“…The asymmetric behavior could also be observed in other simulated works. [16,25] It might be attributed to the insufficient number of domains used in the present study. Temporal evolution of morphological patterns without mechanical loading is shown in Fig.…”
