A discussion was especially made of the material choice for small slant angle experiment. It is shown that all the metallic materials which used to be conventionally employed in such experiments seem to be not most satisfactory. 收稿日期: 1981-03-18      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 龙期威 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I3/253 [1] 1976年北京断裂力学交流会第二次会议文集,1977,p.302,340． [2] Hussain, M.
