Interfacial mixed-mode fracture of adhesive bonds undergoing large deformation
Interfacial fracture of adhesive bonds undergoing large-scale yielding is studied using a combined experimental/ finite-element approach. The full range of in-plane mode mixity is produced over bond thickness ranging from 30 to 500 lm using the scarf and the ENF joint geometries. Novel techniques for introducing pre-cracks and surface decoration, together with in situ observations, facilitate a...
متن کاملMixed-mode Fracture Analyses of Plastically- Deforming Adhesive Joints
A mode-dependent embedded-process-zone (EPZ) model has been developed and used to simulate the mixed-mode fracture of plastically deforming adhesive joints. Mode-I and mode-II fracture parameters obtained from previous work have been combined with a mixed-mode failure criterion to provide quantitative predictions of the deformation and fracture of mixed-mode geometries. These numerical calculat...
متن کاملMixed Mode Fracture Toughness of an Adhesive Bonded Joint
Adhesive joints are continuously emerging as candidate to replace traditional fastening systems, such as riveting or welding, in primary structural applications. A wide class of components belonging to electronic, automotive and aerospace industries contains adhesive joints, however, the reliability during service constitutes a major technical problem as these contain flaws. Therefore, their us...
متن کاملASSESSING ADHESIVE BOND FAILURES: MIXED-MODE BOND FAILURES EXPLAINED By
The level of understanding of adhesive bond failures within the flight safety community is not as robust as it could be. Generally, most investigators are broadly aware of cohesion failure (fracture of the adhesive) and adhesion failure (a slick failure at the interface). They may also have some limited knowledge of common causes for bond failures such as bond-line voids, which is one cause of ...
متن کاملAnalytical modelling of the electromechanical behaviour of surface-bonded piezoelectric actuators including the adhesive layer
The behaviour of a piezoelectric actuator is strongly affected by the bonding condition along the interface between the actuator and the host structure. The current paper represents an analytical study of the static effect of the mechanical and geometrical properties of the adhesive layer on the coupled electromechanical behaviour of a thin piezoceramic actuator bonded to an elastic medium. An ...
