Özet

The area of application of adhesive joints is gradually increasing due to the advantages which provided compared to conventional joining methods. However, especially the stress concentration on the edges of the adhesion zone causes crack initiation and progression, causing failure to the joints. When the studies carried out by the researchers on the single lap adhesive joints are examined, it is seen that the changes in the overlap end geometries affect the joint performance. In studies on cylindrical bonding joints, the performances of the joints under tensile load were generally investigated. In this study, the linear elastic stress analysis under the torsional moment of the shaft-hub connection model, which was originally designed as a cylindrical bonding joint, was performed using ANSYS APDL finite element analysis program. Then, the effects of design changes on the edges of the hub in the new shaft-hub connection models created were investigated by stress and failure analysis. The reason for the torsional moment applied to the cylindrical bonding models created is that the shaft-hub connections are used for torque transfer in machines. As a result of the failure analysis, it has been determined that the reduction of the material at the hub edge increases the failure strength in the adhesion region by reducing the stress concentrations at the edge of the shaft adhesive layer interfaces which is the critical region. The highest strength increase was 30% in Model-4. However, in the new models created, the hub failure strength decreased, and the shaft failure strength did not change. In these working conditions, it was determined that the ideal model was the Model-3 design.
