摘要:主要综述了当前有关叠加于偏场之上的电弹性体小位移问题的求解方法,即偏场方法.首先介绍了作为偏场方法理论基础的非线性电弹性力学理论,接着总结了偏场方法的研究进展以及受偏场作用后,电弹性梁、板、壳结构的分析方法,随后综述了偏场方法的诸多应用:其中,包括在薄壁电弹性结构屈曲分析中的应用、在记时与通信压电谐振器和基于频率漂移原理所设计的声波传感器的频率稳定性分析方面的应用、在非线性电弹性材料系数的测定以及偏场作用下电致伸缩陶瓷特征的分析等方面的应用.最后给出了该领域当前和未来的一些可能的研究课题.全文参考文献166篇.Abstract:This article summarizes the new development of small-amplitude motionssuperposed on finite biasing or initial fields in an electroelastic body,which is called the biasing field method.It begins with a summary of the nonlinear theory of electroelasticity,as the theoretical foundation for the theory of small displacement fields superposed on abias. The development of the theory for small displacement fieldssuperposed on a bias, and the development ofstructural theories for electroelastic beams, plates and shells underbiasing fields are discussed. Applications of the theory for small displacement fieldssuperposed on biasing fields in the buckling of thin electroelasticstructures, frequency stability of piezoelectric resonators for time-keepingand telecommunication, acoustic wave sensors based on frequency shifts dueto biasing fields, characterization of nonlinear electroelastic materials bypropagation of small-amplitude waves in electroelastic bodies under biasingfields, and electrostrictive ceramics under a biasing electricfield are reviewed. A summary of some current and possible future researchtopics in this field is given. The article contains 166 references.
