In the low contact pressure region, however, the fretting fatigue life may show the minimum value in some cases (Maruyama et al., ). Figure shows the relationship between the contact pressure and the fretting fatigue life for a Ti-6 aluminum (Al)-4 vanadium (V) alloy when the applied stress amplitude is constant.
