Bellanger, Etienne (author)This thesis aims to study the design and optimization of composite wing components for aircraft, focusing on the pivotal goal of reducing weight while preserving and enhancing structural performance. This is one of the goals of the COST Action joined in the span of the thesis: CA18203 - Optimising Design for Inspection (ODIN). Within this COST...master thesis 2023

Buiting, Niels (author)Rijkswaterstaat aims to build circularly from 2030 onward, with the purpose of having a fully circular economy by 2050. Therefore, the aim of this study is to design a reusable modular superstructure, with a small span, which can replace an existing so-called volstortligger superstructure. This is a structure that Dura Vermeer often uses and it...master thesis 2023

Santana Martin, María (author)Epoxy resins are one of the most relevant and widely used thermosets in the market covering a wide range of applications. Industries are being forced to quickly transition towards sustainable alternatives due to the pressure from emerging environmental concerns, the depletion of petrochemical supplies, and compliance with environmental...master thesis 2022

Leino, Rene (author)The state-of-the-art design approach of composite structures in Formula One (F1) rely on expensive full-scale crash tests and simple models that cannot describe the underlying physical phenomena during crushing. Although the models can describe the crush forces and resulting accelerations, their predictive capabilities are poor, and several...master thesis 2022

Pereira, Andres (author)A novel twist morphing concept is explored, that exploits the buckling instabilities of slender spar webs integrated into a wing structure to control the twisting response to external loads. The main novelty of the concept is in controlling the effective shear stiffness of the post-buckled slender spar webs through external variable constraints...master thesis 2022

Ouchene, ALI (author)Nowadays, most of the historical bridges (Amsterdam, 2019) of Amsterdam do not meet the load-bearing criteria of the current design code (Eurocode: 2012). This has several reasons. It comes partly because of the overdue of the maintenance (Amsterdam, 2019) but also because the traffic load for which the bridge has been designed, is lower than...master thesis 2021

van der Aa, Mike (author)This work is a part of the Automated Rotor Blade Inspection (ARBI) project. ARBI aims to improve the rotorcraft RTB process with novel rotor blade measurement equipment. The objective of this research is to investigate how the variation in structural properties of the rotor blades composite structure affects the dynamical response during the RTB...master thesis 2021

Germonpré, Flores (author)The collapse of composite stiffened panels in compression is complex and involves the interactions of many different failure modes. However, when the panel is allowed to enter the post-buckling regime, skin-stringer separation due to the interaction of the post-buckling deformations with the skin-stringer interface is often the critical failure...master thesis 2021

Pasvanti, Nikoleta (author)The demand for efficient lightweight structures grows rapidly in the aerospace sector. Topology optimization, introduced in the late 80s, is a method capable of producing such structures and has been mainly studied for isotropic materials. On the other hand, the performance of composite structures, which are already widely employed in the...master thesis 2021

Ganesh Ram, Srinivasan (author)The current generation of commercial aircrafts extensively use composite materials such as Carbon Fibre Reinforced Polymers (CFRP) in both exposed and primary structures. These materials lack through-thickness reinforcement and are hence susceptible to out-of-plane impact damages. Barely visible impact damage caused by low energy impacts poses a...master thesis 2021

Uijterwaal, Paulien (author)The failure of composite laminates is most commonly evaluated through deterministic approaches. However, even though these traditional methods predict the failure well on average, they cannot take into account the inherent probabilistic aspect of failure mechanics. Thus, reliability methods allow for a better structural assessment and improve...master thesis 2021

Thunnissen, Emma (author)Due to current consumption patterns, the world is subject to an environmental crisis. A Circular Economy (CE), “restorative by nature” (Ellen MacArthur Foundation, 2013, p. 14), could mitigate this crisis; however, implementing circularity principles into the lifecycle is not straightforward for many products, including composites. A snowboard...master thesis 2021

Pareyns, Kaat (author)Launch vehicle structures are commonly composed of cylindrical and conical shells, which are inherently sensitive to buckling. The axial compression experienced during launch can consequently be a sizing load case, so it is important to understand the axial buckling behavior of these shells. Experimental testing is an essential part of studying...master thesis 2021

Poorte, Victor (author)This thesis aims to provide more insight into the crashworthiness behaviour of a composite aircraft fuselage. This is achieved by studying both analytically and numerically the crushing behaviour of composite energy absorbers. The analytical model, which is based on energy dissipation rates, generalises previously derived analytical models to...master thesis 2021

Zhang, Jiayao (author)Shape morphing has been considered a future direction in the pursuit of maximised aerodynamic and structural efficiency of an aircraft wing by triggering geometric reconfiguration to adapt to specific design requirements or load environments. Researchers have endeavoured to seek for morphing solutions that are simple, predictable, tailorable and...master thesis 2020

Verhoeven, Alexander (author)In off-shore structures, the jacket foundations are mainly welded connections in circular hollow sections. These connections exhibit problems in resisting fatigue load. Wrapped composite joints tackle this problem with improved fatigue resistance. However, the material properties are yet unknown. In order to determine the properties on a more...master thesis 2020

de Bie, Lisette (author)The Liverpool Metropolitan Cathedral is the Roman Catholic Cathedral in Liverpool. It was constructed between 1962 and 1967, to the 1959 competition winning design of Sir Frederick Gibberd. The roof of the building is crowned by a tapering lantern formed from coloured glass adhered by means of an epoxy-based mortar. This construction method was...master thesis 2019

Grapperhaus, Joep (author)SummaryIntroductionAdditive Manufacturing (AM) offers potential to add value in terms of storage, localised production, production rate, weight reduction, customization and offers complexity for free. Within the Maritime Construction Sector (MCS) business models for AM are difficult to obtain due to its relatively large objects and the...master thesis 2019

Zuurendonk, Bas (author)This report shows the intended process to automatically manufacture Carbon Fibre Reinforced Thermo Plastic (CFRTP) double bend frames. Bicycle rims were chosen as a scaled down representation for difficult to manufacture double bend products. Fuselage frames require a too large facility. The aim is to manufacture CFRTP products in an automated...master thesis 2018
