A R-p-da/dN-ΔK Surface Formula and the Statistical Analysis of Effects of Stress Ratio on Crack Growth for GC4 Steel

Abstract:

surface formula based on stress ratio was proposed in consideration of the effects of stress ratio on fatigue crack growth rate and the scatter of fatigue crack growth. The parameters of surface formula were estimated by using the linear principle of no-linear function. The surface formula was applied on GC4 steel to analyze statistically the effects of stress ratio on fatigue crack growth rate. The results showed that the crack growth rate will increases as the stress ratio increases in the stable stage of fatigue crack propagation for GC4 steel. The increase trend is more obvious when higher reliability is demanded.
