摘要

在初始应力体中电弹性波的三维线性化理论(TLTEEWISB)的范围内,建立了一个数学模型来研究在刚性基础上的时谐力作用下具有初始应力的压电板带的动态响应。采用有限元法求解运动方程的控制系统。研究了不同问题参数相关性的数值结果。特别地,讨论了初始应力参数值的变化对板带动态响应的影响。

A Mathematical Model for Forced Vibration of Pre-Stressed Piezoelectric Plate-Strip Resting On Rigid Foundation
A mathematical model to investigate the dynamic response of a piezoelectric plate-strip with initial stress under the action of a time-harmonic force resting on a rigid foundation is presented within the scope of the three-dimensional linearized theory of electro-elasticity waves in initially stressed bodies (TLTEEWISB). The governing system of equations of motion is solved by employing the Finite Element Method (FEM). The numerical results illustrating the dependencies of different problem parameters are investigated. In particular, the influence of a change in the value of the initial stress parameter on the dynamic response of the plate-strip is discussed.
