Modélisation simplifiée de structures planes élancées collées

Abstract

Within a mechanical structure, the joints ensure the function of load transfer between the structural sub-components. The integrity of the whole structure directly depends on the joint strength. In order to design these critical areas, the load transfer between structural sub-components has to be assessed. The objective of this article is to present approaches for the simplified modeling and analytical and semi-analytical resolutions schemes of adhesively bonded and hybrid (bolted/bonded) joints made of two flat and slender adherends. The macro-element modeling technique is then presented. It allows for the prediction of the load transfer and associated stresses, , especially in the adhesive layer regarded as a cohesive zone.
