本文研究了两条考虑裂纹面接触干涉的等长共面裂纹问题。用边界积分方程法求解了均质各向同性线弹性固体中裂纹在垂直入射拉压波作用下的问题。在一定的波数范围内，研究了裂纹间距对应力强度因子（张开型和横向剪切型）的影响。并与忽略裂纹闭合的结果进行了比较。
In this paper, the problem of two equal coplanar cracks with allowance for the crack faces contact interaction was investigated. The problem of the cracks located in homogeneous, isotropic, and linearly elastic solid subjected to normally incident tension–compression wave is solved by the boundary integral equations method. The influence of the distance between two cracks on the stress intensity factors (opening mode and transverse shear mode) is studied for a range of wave numbers. The results are compared with those obtained neglecting cracks’ closure.
