Effect of pre-stretching on the mechanical behaviour of three artificially aged 6xxx series aluminium alloys
(Peer reviewed; Journal article, 2021)The effect of pre-stretching on the mechanical behaviour of the aluminium alloys AA6063, AA6061 and AA6110 in temper T6 has been investigated. Uniaxial tensile tests and quasi-static axial crushing tests were conducted on ... -
Dynamic anti-icing surfaces (DAIS)
(Peer reviewed; Journal article, 2021)Remarkable progresses have been made in surface icephobicity in the recent years. The mainstream standpoint of the reported anti-icing surfaces yet only considers the ice-substrate interface and its adjacent regions being ... -
Field Station Sandnessjøen, Effect of cracks in concrete after 25 years - Data report
(Research report, 2020)Tre opprissede betongbjelker støpt med forskjellige bindemiddelsammensetninger ble undersøkt etter 25 års marin eksponering ved feltstasjon Sandnessjøen. Betongbjelkene ble undersøkt med tanke på effekten av riss på ... -
A novel tests set-up for validation of connector models subjected to static and impact loadings
(Peer reviewed; Journal article, 2021)A novel test set-up is presented for validation of hybrid connector models between steel and aluminium components subjected to static and impact loading. The proposed components consisted of two hat profiles in steel and ... -
The effect of sodium hydroxide on Al uptake by calcium silicate hydrates (C-S-H)
(Peer reviewed; Journal article, 2020)To reduce the CO2 emissions from cement production, Portland cement (PC) is partially replaced by supplementary cementitious materials (SCM). Reactions of SCM with PC during hydration leads to the formation of Csingle ... -
Synthesis, characterization, and thermodynamic study of selected Na-based zeolites
(Peer reviewed; Journal article, 2020)Zeolites are crystalline aluminosilicates with three-dimensional framework structures that can form in alkali-activated cements, Roman cements, and the interaction zone of cements and clays. However, their stability domains ... -
Thermodynamic study of cement/rock interactions using experimentally generated solubility data of zeolites
(Peer reviewed; Journal article, 2020)Alteration of widespread interfaces between cements and clays in geological time scales is essential to the safety assessment of radioactive waste repositories but not well understood partly due to the low reliability of ... -
The combined effect of potassium, sodium and calcium on the formation of alkali-silica reaction products
(Peer reviewed; Journal article, 2020)Both alkalis and calcium play essential roles in the formation of alkali-silica reaction (ASR) products. Investigation of their combined effect helps to better understand the conditions of ASR. In this study, samples with ... -
Beregningsregler for slanke betongsøyler
(Master thesis, 2021)Det arbeides med en ny revisjon av dagens standard for betongkonstruksjoner, og i denne oppgaven har nåværende og revidert standard blitt sammenlignet gjennom en parameterstudie. Bakgrunnslitteratur for aktuelle tema er ... -

Non-linear behaviour of insufficiently grouted post-tensioned concrete members
(Master thesis, 2021)Denne masteroppgaven har som mål å undersøke de konstruksjonstekniske effektene av manglende mørtel i etteroppspente betongkonstruksjoner. Dette ble gjort ved å gjennomføre ikke-lineære analyser i elementmetodeprogrammet ... -

Fatigue of Concrete
(Master thesis, 2021)Stadige fremskritt innenfor betongteknologi muliggjør bygging av slankere og mer materialeffektive konstruksjoner enn tidligere. Ved økt slankhet blir også påvirkningen fra sykliske laster viktigere og utmattingskapasiteter ... -
Shape and Size of Particles Scaled from Concrete Surfaces during Salt Frost Testing and Rapid Freeze/thaw in Water
(Peer reviewed; Journal article, 2021)Thickness (T), Length (L), Width (W) and size distribution of scaled concrete particles in frost testing were measured. T (mm) increases with particle size surprisingly similarly for different concrete qualities and frost ... -
Carbonation resistance of concrete and mortar containing novel low clinker cement
(Student paper, others, 2019)Corrosion of reinforcement steel is a major deterioration mechanism for reinforced concrete structures. Corrosion can be caused by the carbonation of concrete. In this report we test the carbonation resistance of a novel ... -
On the importance of tunica intima in the aging aorta: a three-layered in silico model for computing wall stresses in abdominal aortic aneurysms
(Peer reviewed; Journal article, 2020)Layer-specific experimental data for human aortic tissue suggest that, in aged arteries and arteries with non-atherosclerotic intimal thickening, the innermost layer of the aorta increases significantly its stiffness and ... -
Thermal transport in polyethylene: The effect of force fields and crystallinity
(Peer reviewed; Journal article, 2021)In this article, we study the local structure and heat transfer properties (thermal conductivity and interfacial conductance) in model semi-crystalline Polyethylene (PE) by non-equilibrium molecular dynamics. We compare ... -
Deep Learning analysis of the LV myocardium in CCTA for identification of patients with significant coronary artery stenosis
(Master thesis, 2021)For pasienter med innsnevring av moderat alvorlighetsgrad i koronararteriene må betydningen av innsnevringen defineres. I klinisk praksis gjøres dette vanligvis gjennom å måle FFR (Fractional Flow Reserve). I denne prosedyren ... -
Development of steady arm damper for electrified railway overhead contact line with double pantographs based on numerical and experimental analysis
(Peer reviewed; Journal article, 2021)To improve the carrying capacity, double pantographs are normally used to collect the electric current from the catenary. The mechanical wave excited by the leading pantograph affects the contact of the trailing pantograph ... -
Heat transfer characteristics of CO2 condensation on common heat exchanger materials, method development and experimental results
(Peer reviewed; Journal article, 2021)Understanding condensation of CO2 is essential for e.g designing compact heat exchangers or processes involved in Carbon Capture and Storage. However, a consistent experimental campaign for condensation of CO2 on common ...
