Fatigue crack growth resistance increases with the loading ratio due to strain-induced crystallization, even if the peak stress increases. Recent experiments have allowed determination of the strain-induced crystallization (SIC) distribution around a crack tip during uninterrupted fatigue tests. The purpose of this work is to compare spatial distributions of crystallinity in a cracked sample at different elongations between one experiment and simulation results based on our model.
