摘　　要：讨论了两个具有初应力的磁电弹半空间界面波的传播特性。在两个不同材料的具有初应力的磁电弹半空间中,由本构方程和控制方程以及界面的连续条件,推导得到两个半空间界面波(Stoneley波)的波速方程。根据对波速方程的数值分析,得到两个具有初应力的磁电弹半空间界面处的界面波的传播特性。研究结果为磁电弹材料在工程中的应用提供理论依据。This article discusses the propagation characteristics of interface(two magneto-electro-elastic half spaces with initial stress)waves.In two magneto-electro-elastic half spaces with initial stress of different materials,the wave velocity equations of interface waves(Stoneley waves)at the interface of the two half spaces are derived from the constitutive equation,control equation,and continuity conditions of the interface of two half spaces.Based on the numerical analysis results of the wave velocity equation,the propagation characteristics of interface waves are obtained.The research results provide theoretical basis for the application of magneto electro elastic materials in engineering.
