Abstract

The main aim of this chapter is to investigate the behaviour of adhesive joints exposed to repeated low-velocity impact, that is, impact fatigue (IF), and to compare this loading regime with standard fatigue (SF), that is, nonimpacting, constant amplitude, sinusoidal loading conditions. Fatigue crack growth using bonded carbon fibre-reinforced polymeric lap strap joints is conducted. It is seen that IF had the potential to initiate a crack and to cause its ...
