Dynamic Behavior of Two Unequal Parallel Permeable Interface Cracks in a Piezoelectric Layer Bonded to Two Half Piezoelectric Materials Planes

  • 摘要: 利用Schmidt方法,研究了压电材料中两个平行不相等的可导通界面裂纹对简谐反平面剪切波的散射问题.利用Fourier变换,使问题的求解转换为对两对以裂纹面张开位移为未知变量的对偶积分方程的求解.数值计算结果表明,动态应力强度因子及电位移强度因子受裂纹的几何参数、入射波频率的影响.在特殊情况下,与已有结果进行了比较分析.同时,电位移强度因子远小于不可导通电边界条件下相应问题的结果.
