摘要

This paper reviews the processes by which fatigue cracks grow and the effects of microstructure.The crack growth processes have been found to be remarkably similar irrespective of microstructure,crack size,or natureof the loading.Large strains at fatigue crack tips applied over repeated cycles may radically alter the general microstructure of a material.Microstructure affects fatigue crack growth kinetics but not the growth processes.
