摘要
对具有中心裂纹或半无限长裂纹的无限大板在集中力作用下得到了精确的复变应力函数。对具有半无限长裂纹的无限大板采用的分析方法是柯西积分。将具有中心裂纹的无限大板的问题化成希尔贝特问题进行求解。
The exact complex stress functions are obtained for a infinite plate with a centrical crack or semi-infinite crack under concentrated forces at a certain point. The analytical method is Cauchy integration for a infinite plate with semi-infinite crack. The problem for a infinite plate with centrical crack is reduced to the Hilbert problem.
