Vos, J. (author)This dissertation explores what road characteristics trigger drivers’ speed adjustments when approaching freeway curves. It combines speed prediction modelling and human factors research methods. The results show that drivers primarily consider visible cues such as the preceding roadway, deflection angle, and the number of lanes, as opposed to...doctoral thesis 2024

Baron, Edward A. (author), Mendoza Cabanzo, Carlos (author), Bento, Ana Margarida (author), Matos, Jose C. (author), Calçada, Rui (author), Gavin, Kenneth (author)Europe’s historic masonry arch bridges are culturally and economically significant, but their long-term safety must be ensured. Scour effects are the most common cause of collapse, so it is necessary to carry out structural assessments to mitigate the risk and prevent potential failures. In this study, a metamodel-based method was used to...journal article 2024

de Raad, B.W. (author), van Lieshout, Marit (author), Stougie, L. (author), Ramirez, Andrea (author)Heat pumps are a promising option to decarbonize the industrial sector. However, their performance at a plant-level can be affected by other process changes. In this work, process changes that improve the heat pump's performance have been identified using Process Change Analysis (PCA), where the background pinch point is used as a reference...journal article 2024

Feng, W. (author), Moreira Arouche, M. (author), Pavlovic, M. (author)In this paper, mode II fatigue crack growth properties of the composite-to-steel interface are characterised through different test configurations, namely ENF and 4ENF tests. Different loading types including force control and displacement control methods are compared. An innovative shear strain based method is proposed for monitoring the...journal article 2024

Romarís Villanueva, Javier (author), Kassapoglou, C. (author)Strain energy release rate calculations for various cases of delaminations emanating from matrix cracks are developed and used to predict the onset of delaminations and their growth size as a function of applied tension and shear loads in composite laminates. The method determines the matrix crack spacing, the delamination onset load, the...journal article 2024

Yu, Ying-Ying (author), Li, Xin (author), Ji, Y. (author)Cubic Bézier curves are widely used in computer graphics and geometric modeling, favored for their intuitive design and ease of implementation. However, self-intersections within these curves can pose significant challenges in both geometric modeling and analysis. This paper presents a comprehensive approach to detecting and computing self...journal article 2024

Leciñana, I. (author), Renart, J. (author), Carreras, L. (author), Turon, A. (author), Zurbitu, J. (author), Tijs, B.H.A.H. (author)The main objective of this paper is to present a delamination benchmark test concept for composite materials that develop non-self-similar delamination in characterization specimens. The non-self-similar delamination is induced by rotating the loading blocks. The simplicity of the test allows for analyzing the loading mode history by...journal article 2024

Amoozandeh, A. (author)Industrial passive exoskeletons have been developed for years as a tool to reduce the physical workload of their users. They accomplish this by compensating for the user’s body weight and decreasing fatigue caused by repetitive loads. Despite their advantages, current exoskeletons have drawbacks that make them less convenient for users and thus...doctoral thesis 2023

Taumaturgo Mororo, L.A. (author)Developing accurate and robust numerical approaches that are capable of modeling fracture in solids has been a challenging undertaking in the computational mechanics community for decades. Models based on a continuous formulation or on a discontinuous one have been proposed by numerous authors, expanding upon abilities and disadvantages of these...doctoral thesis 2023

Viering, T.J. (author)This dissertation focuses on safety in machine learning. Our adopted safety notion is related to robustness of learning algorithms. Related to this concept, we touch upon three topics: explainability, active learning and learning curves.<br/><br/>Complex models can often achieve better performance compared to simpler ones. Such larger models are...doctoral thesis 2023

Amoroso, Pedro (author), Vrcek, Aleks (author), de Rooij, Matthijn B. (author)This study introduces a method based on fine torque control to evaluate traction in rolling—liding line contacts under small slide-to-roll ratios (SRRs). To accomplish this, we engineered an innovative testing machine—a two-roller tribometer capable of precisely applying resisting torques to one of the rollers. Two types of tests were designed...journal article 2023
