Abstract

In this paper, the wave propagation in a functionally graded magnetoelectric coating on a cylinder is studied. Considering the piezoelectricity and piezomagneticity of the coating with an orthotropic symmetry, the wave equations and system matrices for state vector are obtained for SH and P-SV waves propagating along both the axial and circumferential directions. It is found that the wave propagation of the SH wave along the axial direction and the P-SV wave along the circumferential direction is not coupled to the electric and magnetic field, i.e., their corresponding dispersion patterns are same as that for a functionally graded coating without piezoelectricity and piezomagneticity. However, the wave propagation of the P-SV wave along the axial direction and the SH wave along the circumferential direction is coupled to the electric and magnetic field, i.e., their corresponding dispersion patterns depend on the applied electric and magnetic field, their dispersion curves are different under the open and close electric or magnetic boundary conditions.
圆柱体上功能梯度磁电涂层中的波传播
本文研究了圆柱体上功能梯度磁电涂层中电磁波的传播特性。考虑正交各向异性对称涂层的压电性和压磁性,得到了沿轴向和周向传播的SH波和P-SV波的波动方程和状态向量的系统矩阵。研究发现,SH波沿轴向和P-SV波沿周向的传播与电场和磁场不耦合,即其对应的色散模式与无压电和压磁性的功能梯度涂层相同。然而,P-SV波沿轴向和SH波沿周向的波传播是与电场和磁场耦合的,即它们相应的色散模式取决于外加电场和磁场,在打开和关闭电或磁边界条件下,它们的色散曲线是不同的。
