van Dooren, K.S. (author), Tijs, B.H.A.H. (author), Waleson, J. E.A. (author), Bisagni, C. (author)Two aeronautical thermoplastic composite stiffened panels are analysed and tested to investigate the buckling behaviour, the skin-stringer separation and the final failure mode. The panels are made of fast crystallising polyetherketoneketone carbon composite, have three stringers with an angled cap on one side, and are joined to the skin by a...journal article 2023

Baciu, Theodor D. (author), Degenhardt, Richard (author), Franzoni, Felipe (author), Gliszczynski, Adrian (author), Arbelo, Mariano A. (author), Castro, Saullo G.P. (author), Kalnins, Kaspars (author)The Vibration Correlation Technique (VCT) is a non-destructive method to predict buckling loads for imperfection-sensitive structures. While successfully used to validate numerical models and predict experimental buckling loads, recommendations for defining the VCT experiment are scarce. Here, its sensitivity towards the number of load steps...journal article 2023

Cheng, L. (author), Nokhbatolfoghahai, A. (author), Groves, R.M. (author), Veljkovic, M. (author)The performance of the Acoustic Emission (AE) technique is significantly dependent on the sensors attached to the structural surface. Although conventional commercially AE sensors, like R15a and WSa sensors, have been extensively employed in monitoring many different structures, they are unavailable in restricted-assess areas. In contrast,...conference paper 2023

Fernandes, Maria (author), Decouchant, J.E.A.P. (author), Couto, Francisco M. (author)DNA computing is an emerging field that aims at enabling more efficient data storage and processing. One principle of DNA computing is to encode some information (e.g., image, video, programming scripts) into a digital DNA-like sequence and then synthesize the corresponding DNA molecule. Synthesizing this molecule using digital or real human...book chapter 2023

Kool, J.J. (author)In the last century, approximately 100,000 people lost their lives during a flood event and over 1.4 billion people were affected. As the population and economic activities grow in flood-prone areas and the frequencies and intensities of flood events increase due to climate change, damage due to flooding is expected to increase. To limit and...doctoral thesis 2022

Gutierrez Alvarez, J. (author)A big technological leap in Carbon Fibre Reinforced Plastics (CFRP's) has brought to the market materials that are able to operate under severe thermomechanical loading conditions and yet remain lightweight. This is of high interest for new developments in aerostructures, such as supersonic airliners or the hydrogen aircraft. A continuous need...doctoral thesis 2022

Zhang, F. (author)Existing concrete bridges require efficient assessment due to increasing traffic load and degrading material. For reinforced concrete structures without shear reinforcement, a typical failure mode is shear, which often means a total loss of structural capacity and does not have an obvious warning beforehand. To indicate the shear failure before...doctoral thesis 2022

van Kuijk, J.J.A. (author)Fatigue crack growth in metals has been studied intensively for more than half a century. This research field has been closely connected to the engineering industry throughout history. It is therefore no surprise that the main focus has mostly been on developing better prediction models rather than on understanding the phenomenon of fatigue...doctoral thesis 2022

Makridis, Pavlos (author)Indirect illumination is an essential part of realistic computer-generated imagery. However, accurate calculation of indirect illumination comes at high compute costs. To this end, we replace lengthy indirect illumination paths by employing an ambient light cache based on photon mapping principles. By only performing cache queries after a...bachelor thesis 2022

Adams, Maarten (author)Fiber Reinforced Composite (FRC) materials are gaining great popularity in marine structures because of their excellent strength-to-weight ratio, low density, and provided freedom in the design process. However, the use of FRC materials comes along with relatively large uncertainties in material properties and structural integrity after...master thesis 2022

Kreike, Boris (author)The number of raw materials consumed and waste generated by the construction industry is no longer a viable solution in the future. It is required for the construction industry to move from a linear towards a circular economy (CE) by circular construction (CC). The unfamiliarity in actions that need to be taken for CC is still new terrain for...master thesis 2022

Yeh, Jia-Jun (author)Particle sorting is an important step in many biological and biomedical techniques. One sorting technique that has received a lot of attention is based on acoustophoresis. Manipulating cells with acoustic forces allows for a sorting method based on physical properties in a non-invasive, label-free, and biocompatible manner. To date, acoustic...master thesis 2022

Measuring the erosion and deposition parameters that are part of this framework requires time-consuming field observations. Additionally, the erosion parameters are measured independently of deposition...journal article 2022
