| 摘 要： | 研究了磁电弹双材料板(板的上下表面是机械自由、电学开路和磁学短路的)中厚度-扭曲波的传播. 基于磁电弹全耦合的本构方程, 首先推导了厚度扭曲波传播的一般解, 然后利用边界条件和界面条件得到了频率方程. 数值算例分析了压电(BaTiO_{3})-压磁(CoFe_{2}O_{4})双材料板中厚度扭曲波传播时, 位移、电势和磁势的变化特征以及模态数与几何尺寸的关系. |

| Abstract: | This paper is concerned with the thickness-twist waves propagating in an infinite magneto-electroelastic bi-material plate.The upper and lower surfaces of the plate are assumed to be mechanically free, electrically open and magnetically closed.Based on the fully coupled magneto-electro-elastic constitutive relations, the general solutions of the thickness-twist waves are first derived.Then the frequency equations are obtained by using the boundary conditions and interfacial conditions.As an example,for the ... |
