Alcaraz, Mathilde (author)Fibre metal laminates (FML) were initially conceived as a hybrid material, aiming to create synergy between the impact resistance of metals and excellent fatigue resistance of fibre reinforced polymers. The purpose of this approach was to overcome the limitations of single-material structures. However, despite its considerable promise, the use...master thesis 2023

Poliakov, Mykyta (author)Fibre Metal Laminates (FMLs) have been widely utilised in aircraft structures for their specific strength, durability and damage tolerance. Most aircraft structures, due to their size, require joining, and FMLs allow for a special type of joint called the splice, a unique but a lesser known joint.<br/><br/>The bulk of research into the splice...master thesis 2023

Alcaraz, Mathilde (author), Alderliesten, R.C. (author), Mosleh, Yasmine (author)Fibre metal laminates (FML) were originally developed as a hybrid material, to create synergy between the impact resistance of metals and excellent fatigue and corrosion resistance of fibre reinforced polymers, and to overcome the shortcomings of monolithic materials. Yet, the scope of the FML concept is predominantly limited to GLAss REinforced...abstract 2023

Liu, S. (author), Sinke, J. (author), Dransfeld, C.A. (author)Hot-pressing can be an attractive fabrication method that enables the forming of hybrid materials like thermoset based fibre metal laminates. However, the process simulation on press forming requires accurate material characterization and boundary conditions to facilitate part design for a defect-free component. In order to improve the overall...conference paper 2022

Narayanappa, Karthik (author)Joining structural components in aircraft is generally performed through mechanical fastening. The interaction of bearing and bypass stresses in composite bolted joints causes a reduction in the static strength of the joint. The bearing-bypass diagram determines the bearing and net-section failure modes. This thesis work aims to provide a design...master thesis 2021

Alderliesten, R.C. (author)With the introduction of fibre metal laminates (FMLs) as a (fatigue) damage tolerant material concept in aeronautics, an interesting field emerged where fatigue damage interaction plays a dominant role. The hybrid concept effectively demands evaluating fatigue damage growth based on fracture phenomena typical for both metals and fibre...journal article 2019

van Maris, Rutger (author)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...master thesis 2019

van Teeseling, Ivar (author)A new certification approach for bonded primary Fiber Metal Laminate (FML) structures is investigated: using bolts as Disbond Arrest Features (DAF)s to contain the growth of bond line damages so that they can be found and repaired by inspection before becoming critical. By fatigue testing with coupon specimens and model analysis, it has been...master thesis 2019

Zhao, Y. (author), Alderliesten, R.C. (author), Zhou, Zhengong (author), Fang, Guodong (author), Zhang, Jiazhen (author), Benedictus, R. (author)In general, a finite width correction to stress intensity factor (SIF) is required in the fatigue crack growth. The finite width correction factor can be explained physically from the energy point of view. It is assumed that the finite width correction factor primarily constitutes an energy correction factor, i.e. it corrects the applied load...journal article 2018

Wang, W. (author), Rans, C.D. (author), Benedictus, R. (author)Mechanically fastened joints are susceptible to the presence of multiple-site damage (MSD) cracks in the critical fastener row. Different from the MSD growth in joints consisting of metallic substrates, the two coupled metal crack growth and interfacial delamination propagation failure mechanisms in Fibre Metal Laminates (FMLs) make the...journal article 2018

de Haan, Gerardo (author)Bearing-bypass behaviour for composites is different than for metals and therefore this behaviour needs to be re-evaluated. This thesis work aims to provide an initial test set-up to map the bearing- and bypass behaviour in Fibre Metal Laminate mechanical joints, to develop a simple method which can be used by engineers for joint design. This...master thesis 2018

Nardi, D. (author), Abouhamzeh, M. (author), Leonard, R.A. (author), Sinke, J. (author)Gaps and overlaps between pre-preg plies represent common flaws in composite materials that can be introduced easily in an automated fibre placement manufacturing process and are potentially detrimental for the mechanical performances of the final laminates. Whereas gaps and overlaps have been addressed for full composite material, the topic...journal article 2018

Alderliesten, R.C. (author)To further optimize aeronautical structures, an increased level of material hybridization is required. Optimization efforts aim to identify optimal design solutions that satisfy prescribed requirements.

Anisimov, A. (author), Muller, B. (author), Sinke, J. (author), Groves, R.M. (author)Current trends in aircraft design are to increase the economic efficiency by integrating different features in multifunctional materials. One strategy is to embed resistance heater elements between glass-fibre epoxy layers in (heated) fibre metal laminates and to use them as anti or de-icing devices in leading edges of wings. Heated glass...journal article 2018
