摘　　要：研究功能梯度弹性半空间(y≤0)和功能梯度磁电弹半空间(y≥0)界面的Stoneley波传播特性.基于两个介质的本构方程、控制方程和界面连续条件,推导出功能梯度材料界面处的Stoneley波波速方程,通过数值模拟,得到功能梯度材料中Stoneley波的色散曲线,并分析功能梯度材料中Stoneley波传播特性.The propagation characteristics of Stoneley waves in semi-infinite magnetoelectro-elastic media covered a functionally graded semi-infinite space are studied.According to the constitutive equation and motion equation of magneto-electro-elastic materials and the continuous conditions of the interface,the wave velocity equation of Stoneley wave was deduced,and the numerical simulation was carried out by MATLAB to further analyze the propagation characteristics of Stoneley wave in magneto-electro-elastic media.
