本文研究了非均匀介质对静电激励的力学响应。机电耦合问题的控制方程的确定与所需的报表的边界和界面的连续性条件。顺序层压复合材料的类的结果进行了计算，并与相应的有限元模拟和分析估计。这些计算表明，机电耦合可以通过考虑非均匀的机电致动器得到改善。这些发现与最近的实验工作一致，表明EAP致动器的局限性可以通过制造柔性和高介电模量材料的复合材料来克服。
We examine the mechanical response of a heterogeneous dielectric media to electorstatic excitation. The governing equations for the coupled electromechanical problem are determined together with the required statements of the boundary and the interface continuity conditions. Results for the class of sequentially laminated composites are calculated and compared with corresponding finite element simulations and analytical estimates. These calculations demonstrate that the electromechanical coupling can be improved by considering non-homogeneous electromechanical actuators. These findings are in agreement with recent experimental works showing that the limitations of EAP actuators can be overcome by making composites of flexible and high dielectric modulus materials.
