Results show that under the boundary lubrication condition, the contact fatigue crack initiates at the surface and grows into the subsurface in a manner governed by mode II loading, and the orientation of the crack path is controlled by the maximum shear stress at the advancing crack tip. On condition f＝0, the typical crack growing path consists of 4 stages having the shape of the letter U, while it undergoes 3 stages shaped like the letter V on condition f＝0. Generally, the contact fatigue failure results from a series of continuous pitting composed of a stochastic combination of the different stages of a typical crack growth process under conditions f≠0. Key words:  contact fatigue      stress      crack initiation      crack growth.      Received:  18 September 1995      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1995/V31/I9/422 1KanetaM．EUROTRIB85,19852MurakamiY．EngFractMech,1983;17:1933Yamashita．Wear,1983;91:2354LOUBingzhe,HANLining,LUZhenxin,SHENFusan．Fatigue90,Honolulu,1990:6275BryantMD．JApplMech．1982,49:3456GuC,LouB,JingX,ShenF．JHeatTreating,1989:7:9877DowsonD,HigginsonG．ElastohydrodynamicLubrication,PergamonPress,19778黄炎．局部应力及其应用．北京:机械工业出版社,1987:177 [1] BI Zhongnan, QIN Hailong, LIU Pei, SHI Songyi, XIE Jinli, ZHANG Ji.
