Fretting fatigue is a critical solicitation that comes out in many aeronautic
structures as, for example, the blade/disk contact of aircraft engines (Figure 1). It
is characterized by small displacements between two bodies, one of which has an
applied bulk stress. This phenomenon has been studied for a long time [1] and has
been identified to induce damage as well as significantly reduce the fatigue
resistance. Fretting leads to premature crack nucleation compared to classic
fatigue solicitation.
