Elastic behaviour of shrink-fitted forming die assemblies. Part I: Development of an analytical solution

Abstract

The paper deals with the elastic behaviour of the die assemblies obtained by shrinking a thick walled ring onto a finite hollow right circular cylinder in general of different length. Displacements and stresses in the two components of the assembly are evaluated by using the theoretical general solution on the finite thick-walled hollow elastic right circular cylinder with an axially symmetrical load system in terms of Airy's stress function. Radial and axial displacement influence coefficient technique is used to solve the integral equations governing the two extreme frictionless and slipless contact modes at the mating surface.
