| Abstract: | According to the results of test and research for some metal materials in natural gas and petroleum equipments and machines in low temperature environment, a "Standard" and "Normal" has been compiled. It is possible to apply to the safety analysis of fracture engineering at low temperature inthe oil field. In accordance with the "Test technique", ductile fracture toug-hness J_(IC) of metal material at low temperature by using small specimens withcracks can be measured and to convert it to low temperature K_(IC). Besides, itmay be also available for reference when the analysis of low temperaturefracture of machines and equipments for mine, railway, bridge etc. is made. |
