The present paper deals with the estimation of the crack nucleation orientation in fretting-affected Al 7050-T7451 specimens, subjected to cylindrical contact in partial slip regime. In such a context, cracks are generally assumed to nucleate at the contact trailing edge. However, experimental evidences of cracks starting within the contact zone are available in the literature. Therefore, a parametric study on the crack nucleation location is performed in the present work by using an analytical
