Abstract
Adhesive bonding is widespread in several fields, ranging from construction, packaging, automotive industry, aeronautics and medical applications. As a result, it becomes increasingly necessary to reliably estimate their mechanical behaviour. In the context of Cohesive Zone Modelling (CZM), the shear fracture toughness (GIIC) is one of the most influential parameters for the strength prediction. This work aims to make an evaluation of the End-Notched Flexure (ENF) and Four-Point End-Notched Flexure (4ENF) tests to determine GIIC of bonded joints. Three adhesives were tested: Araldite® AV138, Araldite® 2015 and SikaForce® 7752. It was concluded that the GIIC values for each adhesive obtained by the ENF and 4ENF tests are in good agreement.
