Numerical evaluation of the ENF and 4ENF tests for the shear toughness estimation of adhesive joints

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. Modern strength prediction techniques such as Cohesive Zone Modelling (CZM) are based on energetic principles. In the context of CZM, the shear fracture toughness (GIIC) is one of the most influential...
