This paper presents an analysis of the stresses and radial deformations in three elastic disks shrink fitted together to form a rotating assembly. The analytical results derived from this paper assume the three disks to be perfectly circular. The stress distribution as well as the displacement is assumed to be functions of radial coordinate and rotational speed. The thickness of disks is also assumed to be small as compared to their diameters. The results include the radial and tangential stress distribution at the interface for both static disks and for rotating motion of the assembly. The interference fit between the disks is also seen to be a function of rotational speed.
