不同材料拼接的半平面裂纹问题

On Problem of Half-Plane Bonded By Different Materials With Cracks

本文讨论了不同材料拼接的半平面裂纹问题,把问题化为某正则型的奇异积分方程,并采用分析函数的方法,给出了直裂纹情况的封闭形式的解,并导出了应力强度因子的公式。

In this paper, the problem of half-plane bonded by different materials with cracks have bnee discussed. The first, we reduce such problems to a normel singular integral eguation. Then, by means of method of seperation complex Aray function, we obtion the solution in closed form of the elastic materials with straight crack. At last, we provided the formule of the stress facter.
