中文摘要：

为了更好地描述铁电薄膜在外场下的非线性畴变行为,该文提出了铁电薄膜在热-电-力耦合场下的本构模型.该模型基于细观力学模型,认为电畴自由能的改变提供电畴翻转的动力.在铁电材料的本构关系中加入了铁电薄膜制备过程中产生的残余应变项,以便描述铁电薄膜材料在外加热-电-力耦合场下的非线性行为.模型的理论计算结果与实验结果相符,并与其他模型中的计算结果一致.

英文摘要：

To better describe the non-linear domain switching behavior of ferroelectric film,a constitutive model that can be used to predict the thermo-electro-mechanical nonlinear behavior of ferroelectric films has been proposed.This model is based on micromechanical model in which the difference of potential energy is regarded as thedomain switching driving force.The remnant strain that produced during the preparation process is considered into the constitutive relation so as to describe the thermo-electro-mechanical nonlinear behavior of ferroelectric films.The calculated results by the proposed model agree well with the experimental data,and are consistent with the results of other model simulation.
