The evolution of fretting regime, fretting wear mechanism and fretting crack initiation behavior in as-received and shot-peened samples are developed and comparatively evaluated. The effect of shot-peening on crack initiation orientation is elucidated through an analytical approach using fracture mechanic concepts. The results highlight that shot-peening not only changes the fretting wear mechanism and crack initiation angle, but also reduces the crack number and prevents the crack propagation in Ti-6Al-4V dovetail joint specimens.
