摘要

Adhesive bonding represents an efficient way to join two or more structural members. The adhesive bonding technique has been increasingly applied in different industrial sectors because of the many advantages it brings. The fracture behaviour of adhesive joints under quasi-static and the low-frequency fatigue regimes have been extensively studied. On the other hand, there are few studies dedicated to adhesive joints under vibration fatigue regimes at resonance and therefore little information regarding their performance and the failure mechanisms. It can be said intuitively that fatigue life under this regime can be more seriously compromised and therefore it is important to understand the behaviour of bonded joints under this regime.
