中文摘要: |
压电-压磁复合材料或结构的许多应用是与弹性波的传播密切相关的,这要求人们首先从理论的角度弄清楚弹性波的传播规律。本文研究由多个不均匀磁电弹介质组成的薄板厚度扭曲波的传播性质,从磁电弹全耦合场三维方程出发得到了其精确解,根据所得到的解分析了波的传播特征,这些结果对于理解和设计谐振器、滤波器以及声波元件提供了有价值的理论基础。 |
英文摘要: |
Many application of piezoelectric and piezomagnetic compound materials have close connection with the propagation of elastic waves. This needs us firstly gain clear of the laws of elastic waves propagation theoretically. We study thickness-twist vibrations and waves in unbounded, multi-sectioned magneto-electro-elastic plate. An exact solution from the three-dimensional equations of magneto-electro-elastic material is obtained. Wave propagation characteristics are calculated based on the solution. The results are useful in the understanding and design of plate resonators, filters and acoustic wave sensors. |
