摘要
通过与有限元等数值方法及实验结果的比较，说明了关于两共线半无限裂纹问题的新应力强度因子公式的重要工程实用价值。
The new formulae of a class of stress intensity factors, which are suggested from the reexamination of the collinear semi infinite crack problem, are compared with the results of finite element calculations and experiments. It demonstrates the practical importance of the new formulae, and at the same time shows that the old counterparts, which are contained in several important engineering handbooks used all over the world, do not work with practical engineering problems.
