(Peer reviewed; Journal article, 2023)Janus nanoparticles (JNPs) possess great potential in recovering the residual oil from reservoirs, however, the fundamental interaction mechanisms among nanoparticles, the oil, and reservoir wall characteristics remain to ... -
Unravelling the mystery of fish scales in lowering ice adhesion
(Peer reviewed; Journal article, 2024)The influence of static surface properties, such as free energy, toughness, and elasticity, on icephobicity has been extensively researched and documented in existing literature. However, there remains a limited understanding ... -
Updating of numerical models for enhanced dynamic assessment of existing structures - Analysing parameters for model updating of a riveted steel railway bridge, based on the sensitivity method
(Master thesis, 2016)Updating a numerical model of a real structure is an important tool to enhance an existing model, such that it represents the structure more accurately. To assess the current state of a structure, and predict the remaining ... -
The use of a Laguerrian expansion basis as Volterra kernels for the efficient modeling of nonlinear self-excited forces on bridge decks
(Peer reviewed; Journal article, 2021)In the last decade, the bridge aerodynamics community has pivoted towards the investigation and prediction of nonlinear aerodynamic phenomena. Several nonlinear models have been suggested, but the research community has ... -
Use of Concrete for Road Infrastructure: A SWOT Analysis Related to the three Catchwords Sustainability, Industrialisation and Digitalisation.
(Peer reviewed; Journal article, 2019)This paper aims at identifying the direction for more sustainable development of the use of concrete in road infrastructure in an industrialised context. The increase in the global mean temperature is one of the most severe ... -
Use of damage-based mesh adaptivity to predict ductile failure in blast-loaded aluminium plates
(Journal article; Peer reviewed, 2017)This study uses experimental data to evaluate the capabilities of a numerical model in EUROPLEXUS (EPX) to predict ductile failure in thin aluminium plates subjected to blast loading. The loading was generated using a shock ... -
Use of excavated rock material from TBM tunnelling for concrete proportioning
(Master thesis, 2017)This thesis studies the possibilities to utilize excavated rock material from tunnel boring machines (TBM) for concrete proportioning. Available alluvial sand deposits are becoming scarce on a global scale and crushed rock ... -
Using ALE-VMS to compute aerodynamic derivatives of bridge sections
(Journal article; Peer reviewed, 2018)Aeroelastic analysis is a major task in the design of long-span bridges, and recent developments in computer power and technology have made Computational Fluid Dynamics (CFD) an important supplement to wind tunnel experiments. ... -
Using ALE-VMS to compute wind forces on moving bridge decks
(Chapter, 2017)A framework for simulating the forced-vibration wind tunnel experiment using stabilized ALE-VMS techniques has been developed. With a user-defined motion of the bridge deck the problem reduces to a flow computation on a ... -
Using unit cell simulations to investigate fracture due to compression-tension loading
(Journal article; Peer reviewed, 2016)Experiments regarding impact against X65 steel pipes show that fracture typically arises in areas subjected to large compressive strains before tension. Fracture surfaces from these areas are brittle in character despite ... -
