Abstract

This thesis presents a model that is able to predict fatigue crack growth and damage directionality in non-conventional Fibre Metal Laminates (FMLs) in CentreCracked Tension (CCT) specimens. Non-conventional FMLs encompass all FMLs other than standardised ones such as GLARE. FMLs can be made non-conventional by using multiple fibre types, any fibre orientation, multiple alloy types or thicknesses, or a combination thereof. These characteristics provide much more tailorability than standardised FMLs and thereby extend the applicability of FMLs to, for example, door corner reinforcements and wing structures. Contrary to standardised FMLs, the damage in non-conventional FMLs is non-uniform, necessitating the ability to compute the crack growth rate in the metal layers and the delamination at the metal-fibre interfaces separately.
