Assessment of interface failure behaviour for brittle adhesive using the three-point bending test

In the framework of adhesive bonding, assessment interfacial properties has an essential role in determining joints' global responses. Various surface preparations are available for each type metallic substrate. There plenty tests widely used mechanical characterisation to determine and few assess properties. For such a case, specific three-point bending test can be applied examine interactions between On other hand, direct comparison critical force is not always possible because geometrical incompatibility. A practical solution last issue applying coupled stress-energy criterion (CC) since interface independent substrate thickness. Hence, CC macro-element technique were using aluminium alloy 2024-T3 as DGEBA/DETA™ under many preparation conditions. As result, test's overall behaviour was established terms strength (adherence), including incremental energy release rate stress. Thus, this paper read first work towards ability predict failure frame different geometries. conclusion, occurrence or cohesive unstable stable propagation bonded joints sorted classified function
