| Abstract: |
| 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. |
