In fact, a heavy stress concentration in the radial component appears at the edges of the contact zone being more intense in the case of the hub. Many methods have been proposed for relieving the stress peaks. In order to investigate how the stress concentrations are reduced, in this paper, different stress analysis in interference fits with grooved hubs were carried out using the finite element method.The authors wish to acknowledge the financial support provided by the Spanish Institution “Memoria D.
