Predicting mechanical properties of CO2 hydrates: machine learning insights from molecular dynamics simulations
(Peer reviewed; Journal article, 2023)Understanding the mechanical properties of CO2 hydrate is crucial for its diverse sustainable applications such as CO2 geostorage and natural gas hydrate mining. In this work, classic molecular dynamics (MD) simulations ... -
Unconventional growth of methane hydrates: A molecular dynamics and machine learning study
(Peer reviewed; Journal article, 2023)Natural gas hydrate reservoirs in natural settings subjected to external driving forces are deformed and locally dissociated, while they reform due to endothermic dissociation reaction. Here we report a molecular dynamics ... -
Plate and stiffener buckling in transversely loaded steel panels
(Journal article, 2023)Stiffened plates may be loaded by axial forces in two directions, i.e., along and transverse to the stiffeners, by in-plane shear force, and by out-of-plane loads as from traffic or water pressure. Special care must be ... -
Round-Robin Study for Ice Adhesion Tests
(Peer reviewed; Journal article, 2024)Ice adhesion tests are widely used to assess the performance of potential icephobic surfaces and coatings. A great variety of test designs have been developed and used over the past decades due to the lack of formal standards ... -

Plasma Treatment of PDMS for Microcontact Printing (μCP) of Lectins Decreases Silicone Transfer and Increases the Adhesion of Bladder Cancer Cells
(Peer reviewed; Journal article, 2023)The present study investigates silicone transfer occurring during microcontact printing (μCP) of lectins with polydimethylsiloxane (PDMS) stamps and its impact on the adhesion of cells. Static adhesion assays and single-cell ... -
Probabilistic autoencoder-based bridge damage assessment using train-induced responses
(Peer reviewed; Journal article, 2024)Structural health monitoring (SHM) systems have been increasingly employed to continually assess the current state of bridges. However, the vast amounts of sensor data generated by SHM systems, along with constantly changing ... -
Comparative analysis of shear capacity in concrete structures: Eurocode 2 and its revised version
(Master thesis, 2023)Denne studien undersøker overgangen fra Eurokode 2 (EC2: NS-EN 1992-1-1:2004) til dens reviderte versjon, FprEN (FprEN 1992-1-1:2022), med vekt på skjærkapasiteten til betong. Behovet for å oppdatere EC2 etter nesten to ... -
Fourier transform-based method for quantifying the three-dimensional orientation distribution of fibrous units
(Peer reviewed; Journal article, 2024)Several materials and tissues are characterized by a microstructure composed of fibrous units embedded in a ground matrix. In this paper, a novel three-dimensional (3D) Fourier transform-based method for quantifying the ... -
Macro-indentation testing of soft biological materials and assessment of hyper-elastic material models from inverse finite element analysis
(Peer reviewed; Journal article, 2024)Mechanical characterization of hydrogels and ultra-soft tissues is a challenging task both from an experimental and material parameter estimation perspective because they are much softer than many biological materials, ... -
Biomechanics of degenerative mitral valve leaflets: Mechanical behavior, collagen structure, and numerical simulations
(Doctoral theses at NTNU;2023:395, Doctoral thesis, 2023)Degenerative mitral valve disease impacts around 2% of the population and leads to mitral regurgitation because of valvular incompetence. Two distinct phenotypes of degenerative mitral valve disease are fibroelastic ... -
Adhesion strength of tetrahydrofuran hydrates is dictated by substrate stiffness
(Peer reviewed; Journal article, 2023)Understanding the hydrate adhesion is important to tackling hydrate accretion in petro-pipelines. Herein, the relationship between the Tetrahydrofuran (THF) hydrate adhesion strength (AS) and surface stiffness on elastic ... -
Convoluted reciprocity and other methods for vehicle speed estimation in Bridge Weigh-in-Motion Systems
(Journal article; Peer reviewed, 2024)In bridge weigh-in-motion systems, the vehicle speed is a fundamental input parameter for the weighing algorithm. The speed is generally obtained by processing structural responses measured at different locations along the ... -
Monitoring variability in parameter estimates for lumped parameter models of the systemic circulation using longitudinal hemodynamic measurements
(Peer reviewed; Journal article, 2023)Background Physics-based cardiovascular models are only recently being considered for disease diagnosis or prognosis in clinical settings. These models depend on parameters representing the physical and physiological ... -
Data Set from Long-Term Wave, Wind, and Response Monitoring of the Bergsøysund Bridge
(Peer reviewed; Journal article, 2023)Wind, wave, displacement, and acceleration data have been collected in a measurement campaign on Norway’s Bergsøysund Bridge, an end-supported pontoon bridge, between the years 2014 and 2018. The data set is now available ... -
A Comparative Analysis of Orthotopic and Subcutaneous Pancreatic Tumour Models: Tumour Microenvironment and Drug Delivery
(Peer reviewed; Journal article, 2023)Pancreatic ductal adenocarcinoma (PDAC) remains a challenging malignancy, mainly due to its resistance to chemotherapy and its complex tumour microenvironment characterised by stromal desmoplasia. There is a need for new ... -
