Crack propagation experiments were performed on a mild steel side edge notched specimen for various load ranges and stress ratios at constant maximum loads. The life of the specimen increased as the load ratio increased. The crack growth data were analysed in terms of AKeff as a function of stress r

β¦ Synopsis
Ab&W-The effects of stress ratio on fatigue crack growth thresholds and low and intermediate fatigue crack growth r8tes are ex8mined on steels with ferri+pearlii and tempered martensite micros~c~s, tested in air. The analysis of available experimental data shows that simple empirical relationships can be used to describe the stress ratio dependence of thresholds and fatigue crack growth rates. Results also indicate that thresholds decrease linearly with yield strength.

A study of the effect of load ratio, R, on the low crack growth rates and the threshold stress conditions exhibited by five medium carbon steels has been conducted. It was found that decreased values of R retarded crack growth to an increasing degree as a defined threshold for crack growth was appro
A new model of fatigue crack propagation is proposed which takes the effect of cyclic stress ratio into account. In the model it is assumed tbat the fatigue cmck propagation rate is proportional to the absorbed hysterisis energy per stress cyck at the tip of a crsck. The energy is calctdated from st
Centrally cracked specimens of JIS SM58Q and I-IT80 steels were fatigued. The fatigue crack growth rates, da/dn, and the stress intensity threshold levels, AK,, were measured over the range of stress ratio, R, from -1 to 0.8 by the use of an automatic method of continuously decreasing stress intensi
A modification to the model of Weir ef al. for surface reaction and transport controlled fatigue crack growth has been developed to explicitly account for the effect of load ratio on environmentally assisted fatigue crack growth. Load ratio was found to affect principalfy gas transport to the crack
Cychc pre-stress increases subsequent fatigue crack growth rate in 2024-T3Sl ahrminum ahoy. This increase in growth rate, caused by the pre-stress, and the increased rate, caused by temper embrittlement as observed by Ritchie and Knott, cannot be explained by the crack tip blunting model alone. Each
