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 c
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 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
