摘　　要：对新研发的TMCP钢E40-Z35厚钢板进行了低温CTOD试验,结果表明其具有良好的低温韧性。讨论了TMCP钢国际船级社认证中进行CTOD试验的相关问题:包括试验规范的选择、试验温度的确定和试验结果的评价等,同时介绍了CTOD的概念、试验方法、试验过程及其检验试验结果有效性的方法。The low temperature （--20℃） CTOD （Crack Tip Opening Displacement） test for E40-Z35 heavy plate produced by TMCP （Thermo-mechanical Control Process） is performed. The results show that the E40- Z35 steel possesses excellen＇e toughness in low temperature. The problems about CTOD test during international classifying have been discussed, including the choice of test standards, the determination of test temperature and the assessment of test results and so on. The concept of CTOD, the method of CTOD test, the procedure of CTOD test and the approach of inspecting the validity of test results are all presented in the paper.
