Abstract：The fracture surfaces of certain fracture toughness specimens have been ex-amined by SEM. With materials fractured in quasi-cleavage mechanism, the meandistance, ξ, from the pre-crack tip to the site where the quasi-cleavage crackstarts is regarded to be a characteristic parameter. It seems that this related toG_(Ic) and can be used as an important parameter characterizing the stress field ofthe plastic zone. 收稿日期: 1980-01-18      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 孙福玉 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I1/59 [1] Spitzig, W.A., Amer.
