The stress distributions in joints combining adhesives with bolts are analyzed by using axisymmetric theory of elasticity as a three-body contact problem when torsions are applied to the joints. The joints consist of two hollow cylinders and they are fastened by a bolt and nut after being joined with an adhesive. When an external torsion is applied to a combination joint, an increment/decrement of torsion occurs in the bolt. A method for estimating the variation of torsion in the bolt is proposed. In addition, using the interface stress distribution, a method for predicting strength of the combination joint is proposed. The torsional load occurred in the bolt was measured using strain gauges. Strength of the combination joint was also measured. A fairly good agreement was seen between the analytical and the experimental results. It is shown that the increment of torsional load occurred in the bolt is small substantially. It is observed that the strength of combination joint is greater than that of adhesive joints. It is also found that the combination joint strength increases as the intial clamping force increases and that it is greater than that of bolted joints without adhesives.
