bi-linear cohesive zone model (CZM) has been developed to examine the behaviour of Glare™ Fibre Metal Laminate (FML) specimens containing manufacturing defects in typical features such as splices and doublers. In particular the effects of delamination at the metal- fibre interfaces on the buckling characteristics have been examined. A series of specimens with artificial delaminations have been tested under compression for validation. Tests have been monitored using Digital Image Correlation to determine delamination growth and strain energy release rates for use in the model. Acoustic Emission (AE) has enabled detection and location the onset and progression of damage. Preliminary results for Glare 4B specimens incorporating delaminations into both a splice and a doubler are presented. Good correlation is observed between test result and prediction.
