Shrink fits are used frequently in mechanical engineering applications such as in rotating machine elements to
transfer moments [1] or in pressure vessels (which is also known as autofrettage) to reduce stresses in the elements with
the effect of residual stresses [2]. In the both types of these applications, the desired performance of the structures will be
possible when high interface pressure between hub and inclusion is provided and this can be obtained as high interference
d is settled before the montage [3]. The interference is the radial difference between outer surface of the inclusion and
inner surface of the hub measured before the mounting process. This definition and a sample geometry of a shrink fit
prior to the assembly is presented in Figure 1a. It is obvious that deformation and stresses occur in the inclusion and hub
(after the assembly) with the definition of an interference and they will increase for higher interference values. Moreover,
when higher interference values are used, inclusion and hub will behave as partial-plastic. Although plasticization is not
a desired behaviour in the most of the mechanical engineering applications, certain amount of plasticization can be
acceptable in case some critical advantages are provided [4]. In these cases, more complicated elastic-plastic behaviours
of the structures should be modelled and analyzed carefully to prevent undesired failures. These types of investigations
always draw attentions of researchers (e.g. [5-7]).
