| Abstract: | The low temperature failure evaluation curves of 9%Ni steel and three kinds of welded joints were analysed,the JFAC curve was established respectively based on elastic plastic finite element method and the EPRI method,and compared with the common curve in R6 of the third edition.It was concluded that the common curve could be adapted for the failure evaluation of the defects of spherical ethylene tanks. |
