Molecular Insights into Hydrate Adhesion on Surfaces
(Doctoral theses at NTNU;2024:98, Doctoral thesis, 2024)Gas hydrate deposition and subsequent plugging in pipelines pose a significant hazard to the exploration and transportation of deep-water natural gas resources. Deploying passive anti-hydrate surfaces has emerged as a ... -
Numerical modeling of diseased mitral valves
(Doctoral theses at NTNU;2023:273, Doctoral thesis, 2023)In this thesis, we have developed methods to create digital replicas of patients’ mitral valves from echocardiographic images and perform structural simulations in a finite element framework. The methods allow us to study ... -
Numerical Study on Ductile-to-Brittle Transition of Steel and its Behavior under Residual Stresses
(Doctoral theses at NTNU;2019: 227, Doctoral thesis, 2019)The transition of fracture mode from ductile to brittle (DBT) is a crucial phenomenon of structural materials, e.g. body centered cubic (BCC) metals, which are normally brittle at low temperatures or high loading rates, ... -
On the use of a virtual laboratory for aluminium alloys: application to large-scale analyses of extruded profiles
(Doctoral theses at NTNU;2022:199, Doctoral thesis, 2022)The global effort of decreasing energy consumption and CO2 emissions has resulted in an important increase in the use of aluminium in the automotive sector. Aluminium (in the form of aluminium alloys) possesses many ... -
Operational modal analysis of an end-supported pontoon bridge
(Journal article; Peer reviewed, 2017)A comprehensive monitoring system is installed and currently in operation on the Bergsøysund Bridge, an end-supported floating pontoon bridge, collecting data on accelerations, displacements, waves, and wind. Using ... -
Probabilistic modelling of wind induced load effects for suspension bridges with emphasis on long-term extreme value analysis
(Doctoral theses at NTNU;2022:218, Doctoral thesis, 2022)Economic development has gradually promoted an increase in the demand for and size of long-span bridges worldwide. A tangible example of such development is the Coastal Highway Route E39 led by the Norwegian Public Roads ... -
Repeatability in a multiphase pipe flow case study
(Peer reviewed; Journal article, 2021)A high degree of repeatability is most often an underlying assumption for research and development based on multiphase flow experiments. In this paper repeatability in multiphase flow experiments are studied through an ... -
Sandwich panels with polymeric foam cores exposed to blast loading: An experimental and numerical investigation
(Peer reviewed; Journal article, 2020)Sandwich panels have proven to be excellent energy absorbents. Such panels may be used as a protective structure in, for example, façades subjected to explosions. In this study, the dynamic response of sandwich structures ... -
Sprayed concrete - effect of accelerator, cracks and composition on compaction, porosity, strength and water transport properties
(Doctoral theses at NTNU;2023:124, Doctoral thesis, 2023)The research described in this PhD thesis investigated key aspects of sprayed concrete material, with an intention of gaining knowledge to enable greater use of sprayed concrete for permanent tunnel linings. The two unique ... -
Wind forces on bridge decks using state-of-the-art FSI methods
(Doctoral theses at NTNU;2019:180, Doctoral thesis, 2019)Several bridges with span widths that challenge present technology are currently under planning in Norway, and wind effects are among the major concerns. Traditionally, wind-structure interactions are studied experimentally ...
