6. Conclusions This work studied the torsional behavior of aluminum tubular joints by CZM. Initially, validation with experimental data a different loading type was undertaken, showing good results and a maximum deviation between experimental and numerical values of 6.1%. In the numerical work of torsional joints, 3D models were constructed to accurately simulate the torsion effect between tubes. The  xy stress analysis showed a marked difference between L O =20 and 40 mm, with the latter case showing more concentrated peak stresses at the overlap edges. A significant tSI and tSE effect was also detected, with higher values of these two parameters leading to smaller  xy peak stresses. These differences then reflected on M m , in the sense that higher t SI and t SE yielded higher M m , but t SE >2 mm was ineffective due to inner tube yielding leading to premature failure in the adhesive layer. In the end, recommendations are given for the design of tubular joints under torsion, which can be valuable in the mechanical design of structures with these joints. References Adams, R. D. (2005).
