The Effect of Thickness of Plate on Fatigue Crack Propagation Behavior by Indentations
초록
Making Brinell indentations facing each other near the crack tip is very effective method in increasing fatigue life. In this paper, fatigue test was performed after indentation to investigate the effect of thickness of specimen. The results show that fatigue lives increased my making indentation and retardation cycle is inverse proportional to thickness of specimen.
