摘要
对于工程中的裂纹问题运用二维弹性问题的控制方程和Ｋｅｌｖｉｎ问题的基本解，建立了Ｓｏｍｉｇｌｉａｎａ等式及边界积分方程，并利用常值元及线性元对积分方程离散，从而对裂纹区域进行力学分析．文中所给算例，与文献结果吻合较好．
For the problems of cracks in engineering structures, this paper establishes Somigliana formulas and boundary integral equations by applying the control equations of two dimentional elastic problems and the basic solutions to Kelvin problems. Furthermore, using constant elements and linear elements, the paper segregates the integral equations and analyzes the mechanic properties of cracked regions. The numerical examples given in the paper are comparable to the literatures used in the paper.
