本文探讨了四点弯曲COD试验值在评定结构安全上的应用。指出,由于该种情况下COD的发生发展机理与宽板拉伸试验时相一致,同时能自动考虑焊缝匹配影响,因此在评定结构安全性上较三点弯曲CDD试验更为合理。
This paper discusses the application of the four-point bending COD test to evaluate the structural safety. It is pointed out that the CODD is more reasonable to evaluate the structural safety than the three-point bending CDD because the mechanism of occurrence and development of COD in this case is consistent with that of the wide-plate tensile test and the weld matching is automatically considered.
