Abstract

The use of adhesives for joining tubular structures has gained significant attention as a replacement for traditional methods such as welding, brazing, and soldering. Adhesive bonding offers several advantages, including reduced manufacturing costs, extended component life, and lower structural weight. This study aims to investigate the mechanical response of adhesively bonded tubular joints under axial loading. A theoretical model is developed based on the assumption that the adherends shear stresses vary linearly with the radial coordinate. The model is employed to predict both the shear stress distribution within the adhesive layer and the natural frequencies associated with axial vibrations. To validate the theoretical predictions, a finite element axisymmetric model is also developed. A good agreement is observed between the theoretical predictions and the numerical results, confirming the reliability of the proposed approach. Moreover, the theoretical model performs best when the ratio of axial stiffness of the adherends to the shear stiffness of the adhesive is high.
