A shrink-fit peg subject to bending and shearing forces

A plane analysis is carried out of a peg or beam, located in a shrink-fit r ecess within an elastically similar half-plane. The peg is subject to trans verse tip forces, and conditions of separation and slip along the peg-half- plane interface are analysed. This permits design curves for the avoidance of separation to be established as well as conditions for the avoidance of interfacial slip. The former is a requirement for the maintenance of full s tiffness of the joint, while the latter are needed in order to avert the po ssibility of fretting.
