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

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
Fatigue tests have been carried out on edge notched mild steel specimens of various thicknesses. Results are presented showing the effect of thickness on crack initiation, crack growth and the geometry and fractography of the fracture surface. It was found that both crack initiation and crack growth
