On Shrink-Fit Stresses between an Infinite Cylinder and a Finite Hollow Cylinder

Abstract

This paper is concerned with the stress distributions and the displacements arising in an infinite cylinder which is shrink-fitted to a finite hollow cylinder. The three-dimensional elastic theory and the point-matching method are used to calculate the displacements and the stresses of the infinite cylinder and the finite hollow cylinder. An individual case is worked out in which the contact is frictionless an the sufficient friction occurs to cause complete adherence between surfaces in contact. The distributions of the contact stresses and the displacements are obtained for models of various elastic moduli. These are compared with the results obtained from the two-dimensional calculation and those of the shrink-fit problem of an infinite cylinder and a flexible sleeve.
