Abstract: | Tubular adhesively bonded joints are widely used in many industries such as the oil-and-gas, aerospace and automotive. Such joints are often used to mate dissimilar materials. Composite materials, because of their superior specific strength and stiffness and high resistance to corrosion, have also been widely used to form tubular components. When composites are mated to other materials (such as metals) by adhesives, the stress concentration in the adhesive layer becomes even more exasperated due to the mismatch in the mechanical properties of the mating adherends, thus posing further challenges. Moreover, the presence of a delamination in the composite adherend can significantly influence the stress distribution within the adhesive layer; therefore, the assessment of the adhesive layer stresses in the presence of a delamination is of importance, thus forms the main objective of the present work. |
