Effect of stress ratio on fatigue crack growth
Source abstract
Abstract
Crack growth data of 6061–T6 aluminium alloys were analysed to study the effect of stress ratio. The life of the specimen decreased as the maximum stress intensity increased. The data covered R values for 0.0, 0.1, 0.2 and 0.3 and a good correlation was obtained for U = ((13.5 + 6.0)/l000)ΔK + 1.4R. A crack growth rate equation was also developed.
