The Weibull statistical theory was introduced to describe the volume effect of the cleavage fracture stress determined by smooth tensile and notched bend specimens. The temperature dependence of the cleavage fracture toughness and its scatter band of silicon steel is formulated by applying the HRR theory and the Rice-Johnson's stress analysis for the blunted crack tip zone, as well as by combining with the Weibull's statistical model. The experimental data are in agreement with the prediction. 收稿日期: 1983-04-18      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 杜万泉 蔡其巩 罗力更 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I4/71 1 Ritchie, R.
