摘要
讨论了SH波在无限大功能梯度压电压磁材料中共线双裂纹处的散射问题.假定裂纹面上边界条件是电渗透性的,通过建立数学模型并利用Copson方法对问题进行求解,最后通过数值算例讨论了右裂纹尖端的应力强度因子与材料梯度参数等因素之间的关系.
The problem of SH-wave scattering from two collinear cracks of functionally graded piezoelectric/piezomagnetic composite materials is discussed in this paper. Taking account of the permeable boundary conditions, the question is solved by forming a mathematic model and using Copson method. Finally, the relationship between the intensity factor on the top of the right crack and material grade parameters is discussed according to numerical method.
