摘要
本文利用一种新的混合法——光弹性实验与权函数解法相结合求解了孔壁受均匀内压作用偏置圆孔边径向裂纹的应力强度因子,该方法具有简单、经济、精度高等优点,对分析复杂应力场中圆孔边穿透裂纹问题,该方法同样适用,且优点更为突出.
In this paper a new mixed -method-photoelasticity and weight function for the computation of stress intensity factors for crack at a slanting circular hole in a plate by internal even press. The mixed -method, which is simple,econmical and accurate is suitable to analyze a through -the -thickness crack at the edge of a circular hole in a complex stress.
