Its simplicity and accuracy may be available to the industrial laboratories on the requirement of engineering design. 收稿日期: 1981-04-18      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 魏文光 王广生 张中林 陆丁昌 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I4/478 [1] 陈篪等,金属断裂研究文集,冶金工业出版社,1978,p.93． [2] 日本机械学会論文集,№ 358,通常总会講演会,第42期,1976． No related articles found!
