摘要

分析功能梯度压电层/压磁半空间结构中SH波传播特性。功能梯度压电材料沿x2方向按指数形式变化，电学边界条件分为电学短路及开路，基于推导的频散方程数值分析功能梯度压电材料的梯度系数、覆层厚度及边界条件对频散关系影响。研究成果可为研制、设计高性能声波器件提供理论参考。

Abstract

This paper investigates the propagation of SH waves in the layered plate structure consisting of a functionally graded piezoelectric layer and a piezomagnetic half space. The change of the functionally graded piezoelectric material is exponential form along x2 direction. The electrical boundary conditions is short circuit and open. Based on the dispersion equations, the numerical examples are presented to show the influence of variations of material properties, piezoelectric layer thickness and electrical boundary on the phase velocity. The resach results can provide theoretical reference for high performance acoustic devices.
