Recently, joints that combine a shrink fit with anaerobic adhesives have been used in order to increase joint strength. In this study we deal with the stress analysis and strength evaluation of bonded shrink fitted joints subjected to torsional loads. The stress distributions in the adhesive layer of bonded shrink fitted joints are analyzed by using the axisymmetric theory of elasticity when an external torsion is applied to the upper end of the shaft. The effects of the outer diameter and the stiffness of rings on the interface stress distributions are analyzed by the numerical calculations. Using the interface stress distributions, the joint strength was predicted. In addition, the value of the joint strength was obtained experimentally. It is seen that a rupture in the adhesive is initiated from the upper edge of the interfaces when a torsion is applied to the upper end of the shaft. The numerical results show more conservative values than the experimental results. It is found that the joint strength of bonded shrink-fitted joints is greater than that of shrink-fitted joints.
