摘要：
Crack propagation experiments were performed on IS-1020 steel for various load ranges and stress ratios. At constant maximum load, the life of the specimen increased as the load ratio increased. The crack growth data were analysed in terms of DELTA-K(eff) as a function of stress ratio R. The data covered R values of 0, 0.1, 0.2, and 0.3, and a good relation was obtained for U = 0.80 - 0.3R + 0.15R2. A crack growth rate equation was also developed.
