摘要
提出求解圆弧裂纹问题的新方法.无限大平面弹性体的某一圆周上分布有若干条圆弧裂纹,不论无穷远处是否受力都可化成求解一个复势函数边值条件的线性关系问题.利用这一方法,可以很简便地求得无穷远处受双轴拉伸时圆弧裂纹问题的精确解,进而求出应力强度因子和位移场,并可求出圆弧裂纹面上的位移.
A new method for solving circular arc crack problems is proposed. If there are some cracks in the same circular arc in an infinite plane elastic body, no matter whether the stresses vanish at infinity or not, the problems are reduced to a problem of linear relationship of the boundary value. Using this method, the problem with a circular arc crack under uniform biaxial load at infinity can be solved conveniently and accurately. Furthermore, the displacements on the crack surface and the stress intensity factors at the crack tips are obtained.
