Some extraor-dinary type of fracture was found. Several specimens show the same results thatthe fracture can not he classified as "cup and cone" but appears as spirals asshown in Fig 6 and 8 in the chinese text. The fracture starts at center of thespecimen with a small irregular contour having scattered local cones, and thenseems to propagate by tearing off a wedge-shape-sectioned volume of materialalong a plane spiral until the surface is reached. The angle of the wedge neverappears anywhere close to π/2, this implied that the two wedge surfaces are notthe maximum principle shearing planes, therefore this type of fracture can notbe interpreted on the basis of the maximum shear stress criterion. 收稿日期: 1957-02-18      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 陈先保 刘叔仪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1957/V2/I2/179 [1] Ludwik, P.
