摘要

An aerospace structure is built from the assembly of structural sub-components involving joining technologies such as welding, mechanical fastening or adhesive bonding. The function of joints is to ensure load transfer between the structural sub-components. The integrity of the structure directly depends on strength of these joints. In order to design these critical structural areas, load transfer between structural sub-components must be assessed. The objective of this review paper is to present approaches for the simplified modelling and associated resolution schemes of single-lap adhesively bonded and hybrid (bolted/bonded) joints to predict load transfer. We show that the scope of available closed-form solutions is restricted, such that the use of semi-analytical schemes is suitable. Macro-element modelling is then presented. This technique allows the assessment of load transfer and associated stresses, especially in the adhesive layer regarded as a cohesive zone, while enabling the enrichment of the model, making it more representative of the physical reality.
