前言本文是在此钢焊接壳体常规力学性能非破坏性实测计算方法(1)、(2)、(3)发表之后,考虑到按脆断发生计算缺陷最大容限的需要(4),结合产品生产实际条件,做了比较多的试验研究,对防止焊接壳体发生灾难性脆断事故的定量予算方面,提供了在常温状态下、平面应变型、T-S取向、△α等于零时的裂纹韧性值J_(1c)非破坏性实测计算方法。
Preface This article is in this steel welded shell nondestructive measurement of conventional mechanical properties of non-destructive methods (1), (2), (3) published after considering the occurrence of brittle fracture defects according to the maximum allowance (4) The actual conditions of the production, do more experimental research, to prevent the occurrence of catastrophic brittle fracture welding shell calculations, provided at room temperature state, the plane strain type, TS orientation, △ α is equal to zero when the crack toughness Value J_ (1c) non-destructive calculation method.
