Xu, F. (author)In the prevailing context of the 21st century, characterized by a predominant reliance on oil and gas, or in the promising future where green energy shapes a human society committed to net-zero emissions, the role of underground fractured formations in energy production and storage remains pivotal and irreplaceable. Geological faults typically...doctoral thesis 2024

Li, Qiang (author), Wang, Xinquan (author), Gavin, Kenneth (author), Jiang, Shengxiang (author), Diao, Hongguo (author), Wang, Kangyu (author)Extensive studies have been performed on the effectiveness of scour protection against scour erosion progression. But there is little research to date evaluating the effect of scour protection on vertical resistance behaviour of monopile foundations. This paper investigates the influence of scour protection on the vertical loading behaviour of...journal article 2024

Li, Qiang (author), Wang, Xinquan (author), Gavin, Kenneth (author), Jiang, Shengxiang (author), Diao, Hongguo (author), Wang, Mingyuan (author), Wang, Kangyu (author)Scour leads to the loss of soil around monopile foundations for offshore wind turbines, which affects their structural safety. In this paper, the effect of scour on the lateral behaviour of monopiles was extensively investigated using finite element analysis, and calibration and comparison were undertaken using centrifuge tests. Piles with three...journal article 2024

van Bergen, Steven (author), Norte, R.A. (author), Aragon, A.M. (author)The computational analysis of nanophotonic devices is usually carried out via the standard finite element method (FEM). However, FEM requires meshes that are fitted to the devices’ boundaries, so making changes to the geometry (and thus the mesh) results in an inefficient process at best. Such an approach is therefore at odds when conducting...journal article 2024

Adams, M.G.A. (author), Huijer, A.J. (author), Kassapoglou, C. (author), Vaders, Johannes A.A. (author), Pahlavan, Lotfollah (author)The multimodal and dispersive character of ultrasonic guided waves (UGW) offers the potential for non-destructive evaluation of fiber-reinforced composite (FRC) materials. In this study, a methodology for in situ stiffness assessment of FRCs using UGWs is introduced. The proposed methodology involves a comparison between measured wave speeds of...journal article 2024

Hosseini, A. (author)HIsarna is a new and breakthrough smelting reduction technology for producing liquid hot metal for steelmaking directly from iron ores. Compared to the conventional blast furnace route, HIsarna achieves a 20% reduction in CO2 emissions by eliminating coking and the need for iron ore agglomeration processes such as sintering and pelletizing and...doctoral thesis 2023

Egberts, G. (author)Burns can make patients’ lives quite miserable. Apart from prominent and thickened, or hypertrophic, scars, the skin may be characterized by contraction. When this contraction is so severe that the patient loses joint mobility, it is called contracture. Then a patient may have difficulties with sports or other daily activities. The consequence...doctoral thesis 2023

van Zwieten, G.J. (author)A vital component in the management of seismic hazard is the study of past seismic events. Classically, this has been the domain of seismology, which studies the dynamic manifestations of the event to infer properties such as epicenter and moment magnitude. More recently it has become possible to perform similar analyses on the basis of the...doctoral thesis 2023

Singh, Diwakar (author), Sharma, S. (author), Kumar, Rajeev (author), Chauhan, Vishal S. (author), Vaish, Rahul (author)Although conventional actuators like piezoelectric and electrostrictive are efficient, but they required hard wiring, which contaminates the control signal and adds to the weight of the structure. The current study presents a wireless control strategy using photostrictive actuators. Owing to the fortunate combination of photovoltaic effect...journal article 2023

Xu, F. (author), Hajibeygi, H. (author), Sluys, Lambertus J. (author)In fractured geological formations, as a result of the in-situ stress changes, fractures can propagate or slide. This phenomenon can be efficiently modeled by the extended finite element method (XFEM) when there are only a few fractures present. However, geological reservoirs contain many fractures which can also cross and are densely...journal article 2023
