Tubular adhesive connections, which are employed in trusses, pipes, and offshore structures, are similarly subject to the same fundamental notions of adhesive joint designs as apply to flat adherends. This study compares the tensile performance of three adhesives in aluminium tube joints (AW6082-T651) as a function of different overlap lengths (LO). The results of an analytical examination are compared with a numerical analysis using cohesive zone models (CZM) and the experimentally determined joint strength. The analytical investigation was conducted using two different analytical methodologies. The simpler and more direct formulation examined peel (y) and shear stresses (xy) before continuum mechanics criteria were used to assess the joint strength. The CZM results were the most precise, even if the analytical models showed some limits in comparison to the continuum mechanics-based criterion. The global yielding (GY) approach yields findings that are equal to those of the CZM approach, which offers the best approximation.
