Klerks, Joosje (author)In common practice, quay walls are engineered to fulfil their services for a minimum lifetime. However, in many cases, quay walls are designed stronger than minimally required, which means that the quay wall could be able to serve its purpose over a longer period or endure higher loads. In general, the optimization of quay wall designs or the...master thesis 2024

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

3D Shape Optimization of Consecutive Manifolds using Free Form Deformation and Adjoint-Based Methodsvan der Mark, Luuk (author)Current design methods for oblique manifolds were first presented in the paper of London et al. in 1968. This method presents a single equation to shape the dividing manifold of several manifold configurations. However, current literature shows a potential to improve the current design method by implementing advanced techniques. This paper aims...master thesis 2024

(author), Pollitz, Fred (author), Okal, Emile (author), Jeon, Taehwan (author), Seo, Ki Weon (author), Stanaway, Richard (author)Earthquakes involve mass redistribution within the solid Earth and the ocean, and as a result, perturb the Earth's gravitational field. For most of the shallow (<60 km) earthquakes with M<sub>w</sub> > 8.0, the GRACE satellite gravity measurements suggest considerable volumetric disturbance of rocks. At a spatial scale of hundreds of km...journal article 2024

Liu, Q. (author), Ghodrat, S. (author), Jansen, K.M.B. (author)Conventional hinge actuators often face limitations including excessive weight, large size and unpleasant noise. Shape memory alloys (SMAs) offer a solution to address these issues due to their favorable characteristics, such as lightweight, high actuation force and small form factor. However, most existing SMA-based hinge actuators rely on...journal article 2024

Liang, M. (author), Xie, J. (author), He, S. (author), Chen, Y. (author), Schlangen, E. (author), Šavija, B. (author)Early-age cracking risk induced by autogenous deformation is high for cementitious materials of low water-binder ratios. The autogenous deformation, viscoelastic properties, and stress evolution are three important factors for understanding and quantifying the early-age cracking risk. This paper systematically reviewed the experimental and...review 2024

Xu, Fuqiang (author), Shi, Yu (author), Song, Xianzhi (author), Wu, Wei (author), Song, G. (author), Li, Shuang (author)The development of hot dry rocks (HDRs) is of great significance to adjusting energy structure, alleviating energy shortage, reducing pollution, etc. Low-permeability granite is the predominant rock type in deep HDRs, making fractures the primary pathways for fluid circulation and heat extraction. The production of HDRs is significantly...journal article 2024

Mendez-Morales, Mariela (author), Branco, Ricardo (author), Tankova, T. (author), Rebelo, Carlos (author)Wire Arc Additive Manufacturing (WAAM) has gained popularity due to its speed and cost-effectiveness. However, the current knowledge on the cyclic deformation behaviour of WAAM materials is limited. To address this issue, this study investigates the cyclic deformation behaviour of WAAM ER70S-6 carbon steel. Coupons were extracted from printed...journal article 2024
