The effect of stress ratio on fatigue crack growth rate in the absence of closure

A fractographic study was performed on Al-alloy fatigue fracture surfaces produced by programmed load sequences. The load sequences included steps of constant amplitude cycles at three different stress ratios, each step is preceded by a small number of high amplitude cycles designed to avoid the inf...
