Fibre Bridging and Crack Tip Shielding in Glare:Numerical and Experimental Validation
The paper validates the phenomenon of fibre bridging and crack tip shielding in Fibre Metal Laminate (Glare) with the help of numerical and experimental procedures.Laminates,with Mode I cracks of different sizes in all their aluminum layers,are subjected to load-extension test to obtain critical loads for estimation of their fracture toughness.Similarly cracked,plain aerospace aluminum alloy specimens are also tested for fracture.Fracture toughness of Glare laminates is found to be higher than those of plain aluminum alloy specimens.Cracked laminates are finally modeled under critical loads by finite element method for quantification of fibre bridging in them.Crack tip shielding is demonstrated.
