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 ... -
Shear lag effects on global bending moments in a long-span pontoon bridge under self-weight, traffic and environmental loads
(Peer reviewed; Journal article, 2023)The present paper deals with a systematic study of the shear lag effect on the bending moment distribution in girders of representative pontoon-type floating bridges (PTFBs). Comparative and parametric studies for ... -
On the spatio-temporal characteristics of the Portevin-Le Chatelier effect in aluminium alloy AA5182: An experimental and numerical study
(Peer reviewed; Journal article, 2023)The Portevin–Le Chatelier (PLC) effect and its spatio-temporal characteristics in the aluminium alloy AA5182 are studied experimentally and numerically in the current work. An extremely high-frequency camera (up to 1000 ... -
Mechanical behaviour and material modelling of an additively manufactured polymer
(Doctoral theses at NTNU;2023:333, Doctoral thesis, 2023)This thesis presents the characterisation and constitutive modelling of the mechanical behaviour of a commercial additively manufactured polymer produced with the stereolithography process. The first part of the characterisation ... -
Behaviour and modelling of multi-layered joints
(Doctoral theses at NTNU;2023:322, Doctoral thesis, 2023)This thesis concerns the behaviour and modelling of multi-layered joints. The aim of the thesis is to provide a fundamental understanding of the behaviour of mechanical joints and their numerical modelling. The work mainly ... -

Modeling of glass exposed to extreme loadings
(Doctoral theses at NTNU;2023:352, Doctoral thesis, 2023)The interest in the load bearing capacity of glass is gradually increasing as a consequence of increased demand for transparency in buildings and vehicles and more strict safety requirements. Due to the stochastic and ... -
Reviewing the Potential of Phase Change Materials in Concrete Pavements for Anti-Freezing Capabilities and Urban Heat Island Mitigation
(Peer reviewed; Journal article, 2023)This study provides an overview of how phase change materials (PCMs) can improve the resistance of concrete pavement to freeze–thaw cycles and mitigate the urban heat island (UHI) effect. The investigation covers different ... -
Grain refinement of Ti6Al4V by incorporating in-situ TiB nanowhiskers in laser melting deposition
(Journal article; Peer reviewed, 2023)One of the known problems in laser melting deposition (LMD) of alloys is columnar grain morphology and large grain size. Adding reinforcements is generally suggested as a viable approach to tailor the microstructure and ... -
Weinberg’s 3HDM potential with spontaneous CP violation
(Peer reviewed; Journal article, 2023)We study the potential of Weinberg’s Z2 × Z2-symmetric three-Higgs-doublet model. The potential is designed to accommodate CP violation in the scalar sector within a gauge theory, while at the same time allowing for natural ... -
Nonlinear earthquake response of integral abutment bridges on vertical and batter piles: A practical approach
(Journal article; Peer reviewed, 2023)This paper presents a new finite element framework for seismic analysis of IABs (and other similar structures) on vertical and batter piles that takes into account nonlinear soil-structure interaction. A previously developed ... -
