It is also clarified that the conventional understanding about the loading capacity in mitre welding joint being always senior to that in perpendicular one, and its related calculation, as well, seem to be not entirely correct. 收稿日期: 1981-02-18      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 陈亮山 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I2/213 [1] 金属研究所高压容器研究组,金属学报,12(1976) ,37． [2] Satoh, K. and Toyoda, M., Welding J., 54 (1975) , № 9, 311-s.
