Stress Analysis and Strength of Joints Combining Adhesives With Bolts Subjected to Torsions
The stress distributions in joints combining adhesives with bolts are analyzed by using axisymmetrical theory of elasticity as a three-body contact problem when torsion is 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 combination joints, 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 produced 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 occurs in the bolt is small. It is found that the strength of the combination joints is greater than that of adhesive joints. It is also seen that the combination joint strength increases as the initial clamping force increases and that it is greater than that of bolted joints without adhesives.
