Abstract

In this article, the effective piezoelectric d33 coefficient of cellular piezoelectret polymer film is simulated by means of the finite element method. The cellular piezoelectret film is regarded as a periodic material, where the almost ellipsoidal voids produced by biaxial stretch are considered to be scattered periodically. The hollow oblate tetrakaidecahedron is used to model the charged microvoids. The polymer is take to be isotropic and viscoelastic. Representative volume element is adopted and the periodic boundary conditions are implemented. The electrostatic field coupled to the stress through the Maxwell stress tensor is analyzed. The piezoelectric d33 coefficient in the film thickness direction is phenomenologically defined and numerically obtained. Time dependence of the effective piezoelectric d33 coefficient is presented for different void geometrical parameters.
胞状压电驻极体聚丙烯薄膜压电d33系数的时间依赖性:有限元建模
本文采用有限元方法模拟了多孔压电驻极体聚合物薄膜的有效压电d33系数。将胞状压电驻极体薄膜视为一种周期性材料,认为其双轴拉伸产生的几乎椭球状的空洞是周期性散射的。用空心扁圆四面体来模拟带电微孔。这种聚合物被认为是各向同性和粘弹性的。采用代表性体积元,实现周期边界条件。通过麦克斯韦应力张量分析了静电场与应力的耦合关系。对薄膜厚度方向上的压电d33系数进行了现象学定义和数值计算。研究了不同孔洞几何参数下有效压电d33系数的时间依赖性。
