| Abstract: | Fretting causes steep stress gradients, which can lead to premature crack initiation or wear across the surface of contacting parts. Both damage modes are activated depending on the slip condition, which can be defined as partial or gross slip based on relative displacement amplitude and normal load. This article investigates the effect of relative displacement on fretting behavior, as well as the impact of slip conditions on contact stresses. A cylinder/plane contact configuration involving AISI 5200 / Ti − 6 Al − 4 V is considered. Fretting tests are conducted up to 25,000 cycles, within the range of relative displacements from 10 to 50 µm, covering both partial and gross slip conditions. The contact stresses (including contact pressure, shear traction, and stress components) are evaluated using finite-element analysis (FEA), and validated against the classical Hertz–Mindlin theory, as well as equations recently developed by Vázquez for stress components. The findings indicate that an initial increase in the tangential force amplitude Q ∗ , followed by stabilization, is characteristic of a partial slip condition. In contrast, a continuous increase in Q ∗ throughout the fretting loading suggests a gross slip condition. Therefore, the Q ∗ –number of cycles curve serves as a reliable indicator for identifying the sliding condition. Finally, unlike in fretting fatigue, gross slip in plain fretting does not shift the peak stress locations. Furthermore, the stress magnitudes vary from partial slip to gross slip.
