An experimental analysis of mechanical behaviour for aluminium-based fibre metal lam-
inates under compression after impact was conducted. Damage initiation and propagation were
evaluated for critical state and force thresholds. Parametrization of laminates was done to compare
their damage tolerance. Relatively low-energy impact had a marginal effect on fibre metal laminates
compressive strength. Aluminium–glass laminate was more damage-resistant than one reinforced
with carbon fibres (6% vs. 17% of compressive strength loss); however, aluminium–carbon laminate
presented greater energy dissipation ability (around 30%). Significant damage propagation before
the critical load was found (up to 100 times the initial damaged area). Damage propagation for
assumed load thresholds was minor in comparison to the initial damage size. Metal plastic strain
and delaminations are dominant failure modes for compression after impact.
