This paper presents an analytical solution based on four-variable refined plate theory for dynamic analysis of cross-ply composite laminates integrated with piezoelectric fiber-reinforced composite actuator attached to the upper surface. This theory considers parabolic transverse shear strains through the plate thickness. Equations of motion for simply supported rectangular plates are derived using Hamilton’s principle, and Navier’s method is employed to solve the equations. An unconditionally stable implicit Newmark scheme is used for temporal discretization. The accuracy of the present analytical solution is proved by comparing the results with those obtained by the finite element analysis. The effects of different parameters such as thickness-to-side ratio, aspect ratios and types of mechanical and electrical loading on the deflections and stresses are investigated.

基于四变量精制板理论的集成压电驱动器的层压复合板的动力学分析

本文提出了一种基于四变量精制板理论的解析解,用于对集成有压电纤维增强复合材料致动器的交叉层复合层压板进行动力学分析。该理论考虑了通过板厚度的抛物线横向剪切应变。简支矩形板的运动方程是使用哈密尔顿原理推导出来的,并采用纳维尔方法来求解方程。无条件稳定的隐式纽马克方案用于时间离散化。通过将结果与有限元分析得到的结果进行比较,证明了当前解析解的准确性。不同参数的影响,如厚边比,
