摘要
本文简要地介绍了近几十年国内外表面断裂力学理论的发展状况及所取得的一些成果 ,重点介绍了应力强度因子求法和裂纹扩展速率的描述 ,同时对应用于圆柱体上的表面裂纹应力强度因子求法及裂纹扩展速率的描述等方面成果进行了评述。
This paper briefly introduces some research progress and developing status on surface fracture mechanics theory within last forty years,emphasizes to introduce the solutions to the stress intensity factors(SIFs)-K and the description of crack growth rate.New developments and progress of the solutions to the stress intensity factors(SIFs)-K and the description of crack growth rate applied to cylinderial surface crack in recent years are reviewed.
