ten Hoopen, Rick (author)An important durability question is whether military off-road vehicles can cope with the fatigue damage from extreme random, complex, and non-stationary loads for the design life of up to 30 years. An accurate life cycle fatigue damage estimation is essential for military off-road vehicles as the lives of military personnel can depend on a...master thesis 2022

De Jonghe, Thomas (author)High performance continuous fiber-reinforced composites are becoming increasingly important in the aerospace industry. In these structures, internal damage is often created and propagated throughout the lifetime, having a negative impact on the structural properties. In order to allow for condition-based maintenance, there is a need for reliable...master thesis 2020

van Noord, Emma (author)The increasing focus on reducing greenhouse gas emissions has led to the attractiveness of offshore hydrogen pipelines in achieving sustainable energy goals. Hydrogen, as a transport medium for energy, offers a viable alternative for transmitting large amounts of energy from offshore facilities to the shore. By storing hydrogen and subsequently...master thesis 2023

de Korte, Coen (author)Monitoring fatigue damage is complex because ships are designed to crack after 20 years, and typically cracks will only occur after a long time. A novel fatigue damage sensor has been invented to indicate damage in corresponding aluminium welded joints. Fatigue damage is accelerated by introducing a stress concentration in the sensor w.r.t. the...master thesis 2018

Romijn, Kasja (author)Over the past few decades, the Netherlands has built numerous steel railway bridges to improve its infrastructure. The repeated loading from railway traffic makes steel bridges susceptible to fatigue damage. The stress ranges at fatigue-prone locations are generally higher in railway bridges than in road traffic bridges. Due to the limited space...master thesis 2023

Deshmukh, Kaustubh (author)Additive Manufacturing (AM), commonly known as 3D printing, exemplifies the recently emerging processing methodologies that aim to substitute the conventional routes, such as to produce parts with complex geometries and eliminate expensive tooling. AM also allows high degree of freedom and rapid prototyping for functional part optimization. This...master thesis 2020

Douma, Laurens Jan (author)The replacement of conventional generation units with variable renewable energy sources could have a negative impact on the balance of supply and demand of electricity. Moreover, since the variable renewable energy sources are inverter based and therefore decoupled from the grid, the overall grid inertia will decrease. To solve this problem, the...master thesis 2023

Wu, Chun-Yen (author)The increasing focus on sustainable living and the need to reduce dependency on fossil fuels has led to a growing interest in renewable energy sources. Among these, the wind energy sector has not only experienced significant growth in terms of numbers but also in size. Larger turbines lead to more severe leading-edge erosion and further increase...master thesis 2023

Markolefas, Panagiotis (author)The preliminary design of wind turbine support structures within an offshore wind farm plays a significant role in decreasing the costs involved and is pivotal in establishing the wind sector as a leading contributor towards a sustainable future. During the early design stages, the optimization of structural dimensions, which involves a large...master thesis 2020

Rikeros Orozco, Daniel (author)There are several methods to perform fatigue assessment as described by the Eurocode 3 and the International Institute of Welding (IIW). The codes establish the relation between stress ranges and their respective number of cycles until failure of the detail. This method is called S-N curves, however this is based mainly on nominal stresses. A...master thesis 2019

SONG, SIQISONG (author)Low-speed roller bearings are generally in the sheave bearings and turret bearings which are used in the offshore industry under heavy loads. One of the challenges to the integrity of these bearings is the presence of subsurface cracking in the raceways. Downtime cost, which is caused by the failure of<br/>these bearings is significant. Based on...master thesis 2021

Santamaria Gonzalez, Gabriel Andres (author)The potential for developing more efficient offshore wind support structures becomes increasingly critical as the offshore wind sector is faced with challenges such as rising commodity prices and shrinking profit margins. These challenges not only impact the industry’s capacity to meet growing global demand but also hinder efforts to address the...master thesis 2023

Kishoen Misier, R.K. (author)Nowadays, in the Netherlands there are about 600 kilometers of asphaltic revetments lying mainly on sea dikes of which approximately 400 km of dike is covered with asphalt concrete [STOWA, 2011]. Asphalt concrete revetments are applied the most and are mostly of older age. Because of the older age it needs intensive care involving periodic...master thesis 2014

Abrahamse, Marijn (author)Fatigue crack monitoring is essential to Ship and Offshore structures, in order to guarantee structural integrity and safety on board. Regular inspections, which are currently performed manually are hazardous, costly and infrequent. The CrackGuard JIP has the goal of developing a system for reliable monitoring of fatigue cracks based on the...master thesis 2018

Bauer, Q. (author)Previous research showed fracture failure in the outsole of sports footwear. There was no method available for the quantification of the material behavior in with this failure mechanism. Therefor the goal of this research was to develop a mechanical test method for quantification of fatigue fracture behavior of a material when a crack is present...master thesis 2016

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

Ziegler, L.S. (author)Offshore wind energy faces three important trends: (1) wind farms grow in size, (2) monopiles are installed in deeper water, and (3) cost reduction remains the most important challenge. With wind farm size, the importance of variations in environmental site conditions across the wind farm increases. These site variations, e.g. water depth and...master thesis 2015

Malschaert, David (author)In the course of this thesis, a research has been conducted to the application of fracture mechanics on an othotropic steel deck (OSD). Obtaining accurate predictions of crack path and fatigue life assessment were the main objectives for this thesis. As 3D crack propagation modelling in orthotropic steel decks is an arduous task, simpler studies...master thesis 2020
