摘要
Abstract
In recent years,the fracture toughness assessment for small size tubes repre sented by SG heat transfer tubes has received more and more attention.In this study,a type of radial cracked C-shaped specimen was designed to estimate the fracture toughness of TA16 heat transfer tubes.The expressions of stress intensity factor K and J integral were obtained based on elastic plastic finite element analyses.A group of radial cracked C-shaped specimens for TA16 heat transfer tubes were carried out by using normalization method.The test results show that small data dispersions of J resistance curves and conditional initiation toughness JQ are observed,the mean value of JQ is 32.875 MPa · mm,and the standard deviation is 1.377 MPa · mm.关键词
