摘要
在研究孔边应力集中系数的问题中，利用了复变函数方法．设预先满足所有的基本方程的待定复函数，再利用最小二乘法使其满足边界条件，从而解出孔边应力集中系数．
An analytical-least square method is presented for solution of stress concentration factors in finite plates with pin holes. All of the basic governing equations and single valued conditions of displacements are satisfied previously by means of method of functions of complexvariables and all of the boundary conditions are satisfied by least square method. Systematicalnew results of stress concentration factors are given for engineering applications.
