Abstract Nowadays, adhesive bonding gained a lot of presence in the design of mechanical structures in the most varied industries, especially aeronautics and automotive. Such a method of joining has several advantages over more traditional methods such as welding or mechanical joining. These advantages include the weight reduction of the structure and the easiest application of the adhesive. In terms of manufacturing time and cost, this is a versatile method that enables the bonding of different materials, including composites, without damaging the structures to be bonded. Tubular adhesive joints have varying applications, such as in trusses, machine axles, and piping. This work evaluated the torsional performance of a structural adhesive in aluminum tubular joints (AW6082-T651), considering the variation of the main geometric parameters: overlap length ( L O ), and tube thickness. In order to predict the strength, the Finite Element Method (FEM) was used with the Cohesive Zone Model (CZM), whose analysis was based on the analysis of shear stresses (  xy ) and joint strength, measured by the maximum torsional moment ( M m ). Previously, validation with experimental data was carried out. The technique was positively validated, and a significant geometry effect on M m was found. © 2022 The Authors.
