This work features the results of experimental research in determining the limiting length of the bonded single-lap joint of materials of the same thickness, different thicknesses and of hybrid systems of different aluminium alloy sheets. The length of the bonded lap joint is just one of the structural features, critical to the strength of bonded joints, this length depending on the thickness and type of the bonded elements. In the case of single-lap bonded joints there is a limiting lap length exceeding of which should not increase the strength of such joints. This is why the length of a bonded lap joint is critical in terms of strength and application concerns. The length of the lap is not always reflected in practice due to simplification of the analytical relations. What is required is experimental verification of the derived theoretical relations. The tested materials are aluminium alloy sheets, widely used in the machinery, aviation and construction industries.

Bonded joints are used in several industrial applications as a surrogate of more expensive repairs, but their reliability must be ascertained. Failure in a bonded joint mainly occurs in the adhesive due to stress concentrations that directly depend on the adhesive thickness. In practice, it is difficult to ensure a good accuracy of the final adhesive thickness, leading to uncertainty to its spatial variability. This uncertainty greatly influences the strength of the bonded joint. This work deals with one of the main key-issues in bonded joints: the influence of the spatial variations in the adhesive thickness on the reliability of the joint; an excessive shear stress level caused by the adhesive thickness variations may lead to failure. This paper provides reliability analysis by considering the adhesive thickness as a stochastic field. The experimental thickness field is obtained so as to identify the stochastic parameters. These parameters are then introduced in a structural reliability model to evaluate the failure probability. Results show the influence of adhesive thickness uncertainty on bonded joint failure.
