摘要
本文考虑了由两种带周期裂纹的不同材料拼接时的问题,已知每一周期裂纹两侧相对于平动的位移(准周期的)和其上外应力的合主矢量。问题化为在周期裂纹和拼接线上的Hilbert奇异积分方程,并导出了计算应力强度因子的数学计算公式。
In this paper, the second fundamental problem of two bonded planes of different isotropic media with periodical cracks is Considered. The displacements relative to a trans-lation on both sides of each crack as well as the resultant principal vector of external stresses on each crack are given.The problem is reduced to a singular integral equation with Hilbert kernel on the cracks and bonded Lines.The formulas for the stress intensity factors are also derived.
