摘要
在[1]中讨论了不同材料拼接平面裂缝中的数学问题,[2]中讨论了不同材料拼接的周期裂缝问题,在[3]中讨论了带周期裂缝的弹性长条基本问题。本文将讨论不同材料拼接的半平面周期裂缝问题,把问题化为某正则型的奇异积分方程,并采用分拆函数的方法,给出了周期直裂纹情况的封闭形式解,且导出了应力强度因子的公式。
In this paper,the problem of bonded half plane by different elastic mater-ials with a number of arbitrary periodic cracks is considered,It is reduceda nor mal singular integral equation.We have obtained its solution in closedform on the periodic straight cracks.The formula of the stress intensityfactors are also derived.
