... a Brinell hardness test. The indentation from fretting may be less than 13 μm (~0.0005 in.) deep, but the deformation can substantially increase the local fatigue stress and often leads to premature failure. Distinguishing between Brinelling and fretting is not difficult if the analysis is done very...
