Elastic stress distributions in interference fits match the values predicted by pressure cylinders theory only if the two joined parts have the same length. 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.
