摘要
本文首先简述了《金属材料准静态断裂韧度的统一试验方法》(GB/T21143-2007)的应用范围和应用特点,然后重点通过对比GB/T21143-2007和国际标准ISO12135:2002《Metallicmaterials-Unifiedmethodoftestforthedeterminationofquasistaticfracturetoughness》的相关条目,提出我国现行的断裂韧度标准GB/T21143-2007存在的诸多问题,认为该标准需要完善和修改。
The application range and features of GB/T 21143-2007 are described in this article. Ac- cording to the comparisons between GB/T 21143-2007 and ISO 12135：2002, the authors find that there are a lot of problems in GB/T 21143-2007, and the problems should be improved and modi- fied.
