The results show that the time to fracture decreases withthe decrease of dwell period of the load. It was considered that hydrogen transported by disloca-tions significantly effects the hydrogen-induced delayed fracture of the steel. Key words:  ladder waveform loading      dislocation transport      hydrogen-induced fracture      Received:  18 January 1988      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/Y1988/V24/I1/55 1 李保成,赵家萍译。兵器材料与力学,1981;(6) :35 2 Troiano A R.
