Geometric Optimization of Tubular Adhesive Joints by Cohesive Models | Chapter 4 | Technological Innovation in Engineering Research Vol. 4

Although they are infrequently studied, tubular adhesive joints are employed in the pipeline, racing, and construction sectors. In this study, the tensile performance of aluminium tube joints bonded with the adhesive Araldite® 2015 was computationally examined using finite elements (FE) and cohesive zone modelling (CZM), taking into account geometric alterations that can help to increase strength. Due to their general stiffness, tubular joints have bigger bonded surfaces and greater flexural strength. Prior to the numerical analysis, axisymmetric CZM modelling for this purpose was confirmed by comparing experimental data. The geometric modifications examined in this study were an adhesive fillet at the overlap ends, an outside chamfer, and an interior chamfer (both in the adherends). The analysed geometric changes showed notable stress reductions but no notable modifications in maximum load (Pm) due to adherend plasticization.
