Recent work has examined the mechanical behaviour of shrink-fitted shafts. It was postulated that a zone of slip develops at the surface of the socket/substrate interface and advances monotonically with increasing torque. It was also suggested that under cyclic loading conditions, frictional shakedown could occur. This means the assembly can support more torque before slip takes place at the surface than originally thought due to the generation of beneficial residual stresses. This was all considered in a half-space formulation. In this paper, calculations are extended to a finite sized shrink-fit, whose dimensions are prescribed by ISO standards, by using a hybrid dislocation/boundary element formulation. Comparisons are then made with a series of experiments which recorded both the torque-angular displacement response of the assemblies and the failure torque for repeated load cycles.
