Analysis of Torsional Tubular Adhesive Joints using a Numerical Finite Element Approach | Chapter 5 | Research Aspects in Chemical and Materials Sciences Vol. 1

 Tubular bonded joints are frequently exposed to axial or torsional stresses. The weight reduction of the structure and ease of manufacturing are two advantages of this form of connecting over additional welding or mechanical joining. The torsional performance of three adhesives in aluminium tubular joints (AW6082-T651) is compared in this study, which takes into consideration the variation of essential geometric parameters such as overlap length (LO) and tube thickness. To anticipate strength, the Finite Element Method (FEM) was combined with Cohesive Zone Models (CZM). The investigation was based on the maximal torsional moment as a measure of joint strength (Mm). Validation with experimental data had already been completed. Experimental data was used to verify the approach, demonstrating CZM's capacity to represent tubular junctions. Except for LO, Mm showed a substantial geometrical impact. Tube yielding reduced joint strength as tube thickness increased.
