This study aims at evaluating damage process of torsion fretting fatigue behavior of carbon steel using acoustic emission. Acoustic emission (AE) technique was applied to observe the growth of damage in carbon steel specimens under torsion fatigue and torsion fretting fatigue loadings. AE frequency spectrum was clustered into groups. The indicated groups were associated with damage types - crack initiation and propagation, and the accumulation process of clustered AE signals were observed.
