| 摘 要： | 基于线性磁—电—弹性理论,得到了横观各向同性压电压磁功能梯度板中的SH波控制方程。应用勒让德正交多项式级数展开法求得了其渐进解,得到了相应的频散曲线。初步探讨了这种多项式方法在解决此问题时的收敛性。研究了压磁性和压电性对SH波的不同影响,并分析了其影响因素。最后分析了材料的梯度形式对压电效应和压磁效应的影响。

| Abstract: | Based on the linear magneto-electro-elasticity theory,the SH wave governing equations of the transversely isotropy piezoelectric-piezomagnetic functionally gradient plate were obtained.The Legendre's orthogonal polynomial series expansion approach was used to find its asymptotic solution.The frequency dispersion curves for the plate were obtained.The convergency of the method was discussed preliminarily.The influences of the piezoelectric and piezomagnetic properties on the SH wave were investigated and the... |
