A previously proposed equivalent driving force model was modified to account for crack closure for modeling stress ratio, R, dependence of fatigue crack growth in near-threshold regime. A new fatigue crack growth driving force model was established i

Transitional behavior of fatigue crack growth is observed for initial notches located at base metal, weld metal and heat-affected zone of 25Cr2Ni2MoV steel welded joint. Results indicate that both microstructures and load ratio R contribute to the tr

The current state of influence of load ratio, R, on fatigue crack growth (FCG) behavior is thoroughly reviewed. Two main approaches, including crack closure concept and driving force parameter method, when used independently, are found to be short of
