Abstract: Hydrogenassisted fatigue crack growth rates (da/dN) were measured for SA516 Grade 70 steel as a function of stressintensity factor range (خ”K) and loadcycle frequency to provide lifeprediction data relevant to pressure ...

Abstract: Hydrogen-accelerated fatigue crack growth is a most severe manifestation of hydrogen embrittlement. A mechanistic and predictive model is still lacking partly due to the lack of a descriptive constitutive model of the ...
