It is found that there exist two accumulation peaks of hydrogen concentration,one at notch tip and the other far apart from it,either in the cracking direction or in the maximum plastic zone. With the increasing of mode II component,the peak of hydrogen accumulation far from the notch tends to drop and move towards the notch tip. The change of the initial hydrogen concentration in the steel has no dramatical influence on the two peaks of hydrogen accumulation near the notch tip. The redistribution of hydrogen concentration is caused mainly by the gradient distribution of plastic strain and hydrostatic stress near the notch tip.Correspondent：CHEN Lian, Professor,Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110015 Key words:  double hydrogen peak      notch tip      mixed mode loading      non─linear finite element method      Received:  18 October 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/I10/461 1TroianoAR．TransASM,1960;52:542OchiaiS,YoshinagaS,KikutaY．TransIronSteelInstJpn,1975,15:5033YamakawaK,YonezawaS,YoshizawaS．MetallicCorrosion,Int．Congress,Vo1．2,CanadaToronto,1984:25441982;(6):1025RobinsonSL,MoodyNR,CostaJC,PontauAE,GerberichWW．ScrMetall,1990;24:1116Wushiding,ChenLian,LiuMinzhi．ActaMetallSinica,1990;3:3127LiYiyi,MaLuming,LiangGuojun.ChinJMetSciTechnol,1987;3:748SihGC．EngFractMech,1973;5:3659王利,陈廉.分析仪器,1994;(3):910BatheKJ著,张圣坤,韩继文,汪庠宝,杨文华译校,非线性有限元分析ADINA理论文本.上海交通大学科技交流室,198611ChenXiaolie,NakasaKeijiro,EngFractMech,1989;33:13312LiJCM,OrianiRA,DarkenLS．ZPhysChem,1966;49:271P [1] ZHANG Guangping;WANG Zhongguang (State Key Laboratory for Fracture and Fatigue of Materials; Institute of Metal Research; Chinese Academy of Sciences;Shenyang 110015).
