In our model the behaviour of the double cantilever beam specimen ischaracterized by a constant stress intensity factor on condition that cracks in thespecimen propagate under constant displacement conditions. Results obtained froma 4340 steel appear to be in reasonable agreement with the established data. 收稿日期: 1979-03-18      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 董学敏 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I3/392 [1] Mostovoy.
