本文提出了一种用于电磁弹性板静振动和自由振动分析的高阶模型，该模型可用于研究薄板和厚板。广义力学位移的有限元模型为24自由度的单层三角形板壳单元。每个元件层引入两个自由度，一个对应于电势，另一个对应于磁势。得到了不同层合磁-电弹性板的解，以及作为特例的纯弹性板的解。结果与静态和自由振动情况下的替代模型进行了比较。
In this paper is presented a higher-order model for static and free vibration analyses of magneto-electro-elastic plates, which allows the study of thin and thick plates. The finite element model is a single layer triangular plate/shell element with 24 degrees of freedom for the generalized mechanical displacements. Two degrees of freedom are introduced per each element layer, one corresponding to the electrical potential and the other for magnetic potential. Solutions are obtained for different laminations of the magneto-electro-elastic plate, as well as for the purely elastic plate as a special case. Results are compared with alternative models for static and free vibrations situations.
