The energy dissipation during fatigue crack growth

Fatigue failures are a major concern in aeronautics. The growth of fatigue cracks in metallic structures and adhesively bonded joints has been studied for decades. Nowadays, most researchers evaluate and predict the fatigue damage growth rate (da/dN) with empirical and phenomenon based approaches, using Linear Elastic Fracture Mechanics with...

The effects of strain rate and temperature on the fracture behaviour of three structural adhesives

The effects of strain rate and temperature on the fracture behaviour of three structural adhesives (Redux 775, Metlbond 328 and EC 2216) were investigated using Double Cantilever Beam specimens. The test results were presented as critical elastic energy release rate data (G) to investigate whether this parameter could be used to characterize me...
