Abstract：Notch fracture machanics was used to investigate the fatigue crack initiation from the notch tip for medium carbon steels (0.4-0.6 wt-%C). The relationships between the maximum stress range at the notch root, △σ_(max), and the number of cycles before fatigue crack initiation, N_i, have been determined. Furthermore, the threshold stress of fatigue crack initiation, △σ_(max)th, as a function of C content or of yield strength of the steel has been proposed. 收稿日期: 1987-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 林吉忠 刘淑华 吴玉树 李一 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I4/339 No related articles found!
