摘　　要：利用复变方法和解析函数边值问题的基本理论 ,研究一类带孔洞的两个半平面焊接的界面裂纹问题。通过适当的函数分解和消元方法 ,将问题转化为一类简单的Riemann边值问题 ,从而得到弹性体应力函数的封闭解 。In this paper, a class of welding problem of two half plane with interfacial cracks is studied. By the method of plane elastic complex variable and the theory of boundary value problems of analytic functions, the stress functions of elastic body are obtained in closed form and the general expression of stress intensity factors has been given.
