Teeuwen, Eduard (author)It is becoming increasingly clear that the effects of climate change should be decreased or even mitigated. Green alternative sources of energy are being explored, and wind energy emerges as an important option that can be exploited on a large scale. Wind turbines are placed more and more often offshore due to larger and more stable wind...master thesis 2023

Wigchert, Lisanne (author)Annually, around 180,000 cardiac ablation procedures are performed as a result of people experiencing cardiac arrhythmia’s. During this ablation procedure, an ablation catheter is used to scar the problematic cardiac tissue after which the arrhythmia will stop. The ablation catheter is discarded after one single use. Incineration of these...master thesis 2023

Haarbosch, Steven (author)In the Netherlands, the coastlands act as the principal protection against the sea. Without human interventions, the Dutch coast would be eroding due to an imbalance in the sediment budget of the coastal zone. The preferred coastal management strategy is sand nourishment, which have become larger in scale and more complex over the last 70 years....master thesis 2023

Scheer, Matthijs (author)Across the Netherlands close to 70 prestressed concrete T-beam bridges with cast-in-between slabs and transverse prestressing built in the 60's and are still in service. The current code NEN-EN 1992-1-1+C2:2011 assesses the shear capacity more conservatively. In addition, the NEN-EN 1991-2+C1:2015 prescribes an increased traffic load. This...master thesis 2023

Peijen, Arjen (author)Topology optimization is a valuable tool for the optimization of all kinds of structures. It can create highly efficient but complex designs. This complexity can make these structures challenging to clean. However, cleanability is often a requirement in, for example, the medical or food industries. Currently, no method exists to reduce the...master thesis 2022

Pavlidou, Stella (author)In an urban context that needs to be constantly adapted to global crises, population movements, climate change and economic crises, designers and engineers strive to configure solutions that respond to multiple criteria. Within this framework, the concept of generative design is gaining more and more ground in the construction field, allowing...master thesis 2022

Liu, BAOLIAN (author)With the advent of Computer-Aided Design, the design and fabrication of complex free-form shells have become easier to achieve. However, this results in extensive usage of custom-made formworks for the production of shell components and falseworks which provide support for the shell during the construction process. Therefore, a modular design...master thesis 2022

Kools, Pieter (author)To design more efficient sailing boat sails and to analyze the efficiency of a sail trim on the water, it is very helpful to have the ability to obtain a digital copy of real-life sail configurations. As a step towards obtaining such digital copies, the Sailing Innovation Centre in collaboration with GeoDelta has created point cloud measurements...master thesis 2022

Lindemann, Thomas (author)The following work focuses on giving an appreciation of gridshell performances at an early stage of design. It has per goal to implement a tool that will orient the user toward a set of possible “best performing” designs. The aspects of interest in this trade-off exploration are the global warming potential, time of fabrication and construction,...master thesis 2022

Isufi, Fiori (author)The motivation of the thesis relates to designing grid shells over existing buildings. Grid shell roofs are a way to enclose an existing space structurally efficiently and have minimal interference with the surroundings from an architectural and environmental perspective. The solution results in less material usage than shell structures, and...master thesis 2021

van der Lans, Daan (author)Elastically neutrally stable structures are compelling within the field of compliant mechanisms, since no force is required to deform them. Several examples of this state of elastic neutral stability exist, which often use equal but opposing structures to balance internal forces. This thesis is on the design of an active neutrally stable...master thesis 2021

LI, CHULONG (author)A new approach to applying the finite difference method for solving the shell model problem. By solving the general shell differential equations (Sanders-Koiter equations) with first-order finite-difference approximation only, a finite difference algorithm called shell code has been developed. <br/><br/>To this end, a 1200-line Python program...master thesis 2021

Palla, Pallavi (author)The gas production in the Groningen gas field of the Netherlands has caused a significant amount of shallowhuman induced earthquakes. Among various building typologies, Groningen is home to many Dutch historical churches constructed by unreinforced masonry which has shown to be highly vulnerable to these earthquakes. From the perspective of...master thesis 2021

Karagiannis, Thomas (author)The usage of tanks has been quite common throughout the industry during the last decades. They fall into the category of shell structures and this is how they need to be studied. The focus of this thesis is concentrated on ground based thin cylindrical tanks filled with water made out of steel. Thin shells are susceptible to buckling, a...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
