Molenaar, Lennart (author)This research is about which geometry of FRP slabs is the most optimal, in terms of costs, to use for a given load and boundary conditions taking the occurring uplift bolt forces into account. The first part of the report focuses on the calculation of the uplift forces in the bolted connections caused by the moving loads. For this, first a...master thesis 2022

van Leengoed, Berend (author)Traditional manufacturing techniques for hydrogen pressure vessels have inherent constraints in the possible geometrical and structural optimisation. Using 5-axis Additive Manufacturing (AM) allows for a far greater shaping freedom. This thesis will provide a new manufacturing method for pressure vessels with 5-axis AM. Using the highly...master thesis 2022

Otte, Stan (author)In this thesis report, the potential for high-throughput fabrication of micromechanical metamaterials is studied. Metamaterials are structures typically consisting of repetitive micrometre-sized features that introduce new and extraordinary ‘material’ properties. However, up to now these structures are predominantly fabricated with slow 3D-print...master thesis 2022

de Lange, Milou (author)Nano-carriers have the potential to be an enormous game-changer in medicinal drug delivery systems. The polymeric nano-carriers used in this study are a product of the self-assembly of amphiphilic block copolymers, a complicated process which must be understood completely to finely tune the desired morphology for drug delivery. The goal of this...bachelor thesis 2022

Alberts Coelho, Alexsander (author)The building stock and the construction industry combined are responsible for a large share of greenhouse gases emissions. At the same time, every year tons of wood, paper and agricultural residues are wasted instead of recycled and upcycled into the production chain. In the fabrication field, the relevance of additive manufacturing processes is...master thesis 2022

Mudunuru, Nanditha (author)Designing and modeling compatibilized polymer blends require accurate interface model. In addition, it is possible that crazing occurs during failure of the interfaces leading to large deformation prior to complete failure and therefore must be accounted for by the interface model.<br/><br/>A preliminary literature review showed that existing...master thesis 2022

Nilsen, Lars (author)Morphogenesis of living organisms could be used as inspiration to digitally augment the reinforcement of structures. The design space in terms of fiber orientation was enlarged to facilitate more complex patches with improved performance that can be 3D printed using a ghost ply optimisation. Simulations performed on optimized open-hole tensile...master thesis 2022

de Jong, Rémy (author)Microfluidic extraction is a promising alternative for existing extraction methods of radioisotopes due to the high surface-to-volume ratio. When assessing the compatibility of microfluidic material with the extraction system, there are three critical aspects—compatibility with organic solvents, compatibility with the radiochemistry, and, most...master thesis 2022

Ros, Vito (author)Ageing of infrastructure leads to an increasing demand for new technologies and design solutions in current bridge engineering. Over the last decades the traffic intensity has grown tremendously, while design codes and regulations have become stricter. Many current steel bridges realised in The Netherlands suffer from fatigue problems....master thesis 2021

Wiltink, Anniek (author)On the road towards developing truly self-healing polymer coatings, autonomous gap closure behavior is an important step. Stored entropic energy in a polymer could act as driving force for this closure. To make proper use of this concept it is important to develop characterization protocols able to relate entropy release to gap closure dynamics...master thesis 2021

Koetsier, Mathieu (author)The increase in road traffic intensity and loading capacity of a truck over the last decades causes fatigue problems in existing bridges built in the 1960s and 1970s. For steel bridges, this means that the deck structure does not meet the current demands. A solution would be to replace these existing deck structures with Glas Fibre-Reinforced...master thesis 2021

Mao, Jinjie (author)In this study, we introduce the Delft Advanced Research Terra Simulator (DARTS), which employs the Operator-Based Linearization (OBL) approach to provide efficient and precise solutions for non-linear discretized equations, to simulate the polymer flooding process. This compositional simulation framework is feasible for describing complex...master thesis 2021

Combe, Christopher (author)The global climate agreement signed in Paris in 2015 sets the goal of limiting global warming, which is essential of saving the planet for future generations. The energy transition from a fossil-fuel living to a sustainable society depends on the technological development of using the renewable energy sources on earth. Wind and solar are common...master thesis 2021

Storm, Joep (author)Designing engineering structures relies on accurate numerical simulations to predict the behaviour of a structure before its realization. In the design process, many variables influence the final structure. There is an incentive for optimizing the design based on the desire for cheaper structures and less material usage. Although a wide variety...master thesis 2021

Daan, Boris (author)For steel flexures, complex geometries are required to reach high support stiffness and limit axis drift over large ranges of motion. These complex flexures are expensive and difficult to manufacture. This paper presents a method of designing short, polymer wire flexures with high support stiffness and modelling their axis drift using a novel...master thesis 2020
