A shrink-fit peg subject to bending and shearing forces

摘要

A plane analysis is carried out of a peg or beam, located in a shrink-fit recess within an elastically similar halfplane. The peg is subject to transverse 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 stiffness of the joint, while the latter are needed in order to avert the possibility of fretting.
