The influence of delamination size on fibre reinforcement in fibre metal laminates
(English)Manuscript (preprint) (Other academic)
Research has been carried out to investigate the influence of delamination size for crack growth behaviour of glass fibre reinforced aluminium laminates (GLARE®). The aim of this work has been to investigate to what degree the restraining fibres in the wake of a metal fatigue crack carry load, and to what extent the size and shape of the delamination will affect the magnitude of the fibre-reinforcement. Tests for different delamination shapes by measuring the stiffness change when restraining fibres are removed has been performed and compared with finite element analysis. The investigation shows that the fibres can be assumed to have a constant stress through the metal crack length, and that a smaller delamination gives a higher restraining effect.
