1-Dimensional Modeling of Cerebrospinal Fluid Flow in Penetrating Arteriole Perivascular Spaces
(Master thesis, 2024)Fjerning av avfallsprodukter fra hjernen er avgjørende for hjernehelse. En forståelse av flyten av cerebrospinalvæske i det perivaskulære rommet rundt hjernevaskulaturen er viktig for å forebygge og bekjempe sykdom, og på ... -
25 years of field exposure of pre-cracked concrete beams; combined impact of spacers and cracks on reinforcement corrosion
(Peer reviewed; Journal article, 2021)The state of corrosion of three pre-cracked concrete beams was investigated after 25 years of marine exposure (atmospheric, tidal and submerged). The influence of inadequate plastic spacers was found to overrule the possible ... -
3D Integration technology: Status and application development
(Journal article; Peer reviewed, 2010)As predicted by the ITRS roadmap, semiconductor industry development dominated by shrinking transistor gate dimensions alone will not be able to overcome the performance and cost problems of future IC fabrication. Today ... -
3D patient-specific numerical modeling of the soft palate considering adhesion from the tongue
(Journal article; Peer reviewed, 2018)Collapse of the soft palate in the upper airway contributes to obstructive sleeping apnea (OSA). In this study, we investigate the influence of the adhesion from the tongue on the soft palate global response. This is ... -
3D Scanning of Corroded Mooring Chain
(Master thesis, 2016)This thesis is concerned with mooring line failure and 3D representations of corroded chain surfaces. Equipment for making such representations have been evaluated through a feasibility study carried out at NTNU. An ATOS ... -
5 years of in situ reinforcement corrosion monitoring in the splash and submerged zone of a cracked concrete element
(Peer reviewed; Journal article, 2021)Results of more than 5 years of in situ reinforcement corrosion monitoring are presented including continuous measurements of concrete resistivity, temperature, and open circuit corrosion potential measurements. Depth ... -
5D Byggeprosess: Modellbasert prosjektstyring
(Master thesis, 2011)Sammenlignet med industrielle produksjonsprosesser sliter byggebransjen med sløsing av tid og ressurser som følge av dårlig kommunikasjon og lite eksplisitt prosjektstyring. Bruk av bygningsinformasjonsmodeller kan vurderes ... -
A combined isotropic, kinematic and distortional hardening model for aluminum and steels under complex strain-path changes
(Journal article; Peer reviewed, 2018)In this work, a new model is proposed for predicting stress transients caused by strain path changes. The model is formulated in stress space, where a second order tensor, i.e., the microstructure stress deviator, is used ... -
A Combined Precipitation, Yield Stress, and Work Hardening Model for Al-Mg-Si Alloys Incorporating the Effects of Strain Rate and Temperature
(Journal article; Peer reviewed, 2018)In this study, a combined precipitation, yield strength, and work hardening model for Al-Mg-Si alloys known as NaMo has been further developed to include the effects of strain rate and temperature on the resulting stress–strain ... -
A Comparative Study Between the Finite Element Analysis and the Isogeometric Analysis Within a Parametric Environment.
(Master thesis, 2022)Vanlig praksis for en design prosess i dag, er at arkitekter og ingeniører jobber i ulik programvare. Det er derimot fordelaktig med et tett samarbeid, for å kunne skape visuelt pene og strukturelt smarte design. I et ... -

A comparative study of beam element formulations for nonlinear analysis: corotatinal vs. geometrically exact formulations
(Chapter, 2017)In this work the geometrically exact three-dimensional beam theory has been used as basis for development of a family of isoparametric higher order large deformation curved beam elements. Geometrically exact three-dimensional ... -
A density-dependent failure criterion for concrete
(Journal article, 2016)This work focuses on the large effect of small secondary stresses on the compressive strength of concrete. The strength and especially the ductility of structural concrete members depend on local triaxial stress conditions ... -
A dynamic analysis of Skuteviksboder in Bergen and alternative load-bearingsystems
(Master thesis, 2010)A seismic analysis of Skuteviksboder is carried out by a simplified hand calculation in addition to a computation by the analytical program FEM-design. Alternative load-bearingsystems are discussed as well. The theory that ... -
A family of hyperelastic models for human brain tissue
(Journal article; Peer reviewed, 2017)Experiments on brain samples under multiaxial loading have shown that human brain tissue is both extremely soft when compared to other biological tissues and characterized by a peculiar elastic response under combined shear ... -
A framework for estimating the implicit safety level of existing design codes
(Chapter, 2017)Target safety levels ( t ) are key elements for reliability-based design and calibration of design codes. They are derived by monetary optimization or from existing codes. The current article discusses these two approaches ... -
A gradient-based multiaxial criterion for fatigue crack initiation prediction in components with surface roughness
(Journal article, 2018)The current study presents methods to predict the governing crack initiation site and fatigue crack initiation life of components with surface roughness. The surface topography is measured with white light interferometry ... -

A Lode-dependent Gurson model motivated by unit cell analyses
(Journal article; Peer reviewed, 2017)In this study, the effects of including a dependency on the third deviatoric stress invariant in the void evolution equation of the Gurson model are examined using unit cell calculations and imperfection band analyses. ... -
A method for determining material's equivalent stress-strain curve with any axisymmetric notched tensile specimens without Bridgman correction
(Journal article, 2017)Large deformation analyses of problems such as plastic forming, ductile fracture with finite element method need a full range of material's equivalent stress-strain curve or flow stress-strain curve. The equivalent ...
