Propagation of Love Waves in an Initially Stressed Functionally-Graded Magneto-Electro-Elastic Materials

研究初应力下含磁电弹覆盖层的半无限大功能梯度磁电弹介质中Love波的传播问题.在电磁学开路和短路的边界条件下,基于初应力下功能梯度磁电弹材料的运动方程,应力自由的表面条件和连续的界面条件得到了Love波的波速方程,为功能梯度磁电弹材料表面波器件的发展提供了理论依据.

The propagation behavior of Love wave in a homogeneous magneto-electro- elastic layer of finite thickness over a functionally-graded magneto-electro-elastic half-space under the initial stresses is investigated. Based on the magneto-electro-elastic theory, the mechanical traction-free surface conditions and the continuous interface conditions, a velocity equation of Love wave is derived umder the electrically or magnetically open circuit and short circuit boundary conditions. The results provide a theoretical basis for the development of functionally-graded magneto-electro-elastic devices.
