Abstract: The crack-line stress field method, which was proposed by Pro. Yi Zhijian^[1], is appied to derive stress intensity factors (STFs) of an eccentrically cracked tension strip. It is pointed out that the result of Ref.[1] is partially erroneous. The correct result is given in the present paper, a comparison with the result from classic literatures [2, 3] is also given. It is shown that Yi's method can be used effectively for the SIF solution of an eccentrically cracked tension strip.

Key words: Stress intensity factor, eccentrically cracked tension strip, cracked-line stress field method

摘要： 用易志坚提出的求应力强度因子的裂纹线应力场方法分析了拉伸偏心裂纹板的应力强度因子,指出文[1]对此问题的分析结果部分有误,本文给出了正确结果,并与经典文献[2,3]的结果进行了比较,说明了此方法对研究拉伸偏心裂纹板的应力强度因子是有效的。
