Optimization of Shell Structures
(Master thesis, 2022)Skallkonstruksjoner er relativt populært blant folk, men samtidig veldig komplisert å beregne og prosjektere. Dette krever mye tid til å nå et godt skall som kan tilfredsstille arkitektene. Dette er selvsagt ikke en rett ... -
Application of a New Empirical Model for Rheology Prediction of Cement Pastes Modified with Filler from Manufactured Sand
(Journal article; Peer reviewed, 2021)There is a need for simple but precise prediction models for proportioning concrete with manufactured sand, for use in ready-mix concrete production. For the last two decades, the particle-matrix model has been used in ... -
Estimating and Predicting Dynamic Properties of Stress-laminated Timber Bridges
(Master thesis, 2022)Populariteten til tverrspente limtrebuer har økt den siste tiden grunnet rask byggetid og god tilpasningsevne. Treverk er betraktet som et karbonnøytralt byggemateriale og dermed ansett som et sentralt byggemateriale for ... -
Beyond the chloride threshold concept for predicting corrosion of steel in concrete
(Peer reviewed; Journal article, 2022)All existing models to forecast the corrosion performance of reinforced concrete structures exposed to chloride environments are based on one common theoretical concept, namely, a chloride threshold, as a sharply defined ... -
Dynamic Response of an End-Supported Pontoon Bridge due to Wave Excitation: Numerical Predictions versus Measurements
(Peer reviewed; Journal article, 2021)Herein, numerical predictions of the dynamic response of an existing floating pontoon bridge are compared with the measured dynamic response. Hydrodynamic coefficients that describe the fluid-structure interaction and the ... -
Ag Nanoparticle-Coated Polystyrene Microspheres for Electromagnetic Interference Shielding Films with Low Metal Content
(Peer reviewed; Journal article, 2022)The fabrication of thin composite films incorporating metal-based fillers with a delicate structure to achieve high electromagnetic interference shielding effectiveness (EMI SE) at low metal content remains a great challenge. ... -
A microstructure informed and mixed-mode cohesive zone approach to simulating hydrogen embrittlement
(Peer reviewed; Journal article, 2022)Hydrogen induced failure under uniaxial tension is simulated in a duplex stainless steel considering microstructural feature of the material. There are three key ingredients in the modelling approach: image processing and ... -

Confinement in bending of high-strength lightweight aggregate concrete beams
(Journal article; Peer reviewed, 2022)The use of lightweight aggregate concrete (LWAC) is limited as a mainstream construction material in structural applications due to more brittle post-peak material behavior and uncontrolled crack propagation compared to ... -
Finite element analysis of mitral valve annuloplasty in Barlow's disease
(Peer reviewed; Journal article, 2022)Barlow’s Disease affects the entire mitral valve apparatus causing mitral regurgitation. Standard annuloplasty procedures lead to an average of 55% annular area reduction of the end diastolic pre-operative annular area in ... -
Limtre av furu utsatt for utmatting i skjær, og statisk skjær i kombinasjon med ortogonal strekk
(Master thesis, 2022)Utmatting av trekonstruksjoner er et relevant tema i byggenæringen, der det bygges store bruer og høye bygninger i tre. Det kreves derfor gode modeller til å dimensjonere trekonstruksjoner for utmattingslaster. De eksisterende ... -
Limtre av furu utsatt for utmatting i langsgående skjær, og statisk langsgående skjær i kombinasjon med ortogonal strekk
(Master thesis, 2022)Sammendrag Utmatting av trekonstruksjoner er et relevant tema i byggenæringen, der det bygges store bruer og høye bygninger i tre. Det kreves derfor gode modeller til å dimensjonere trekonstruksjoner for utmattingslaster. ... -
Performance investigation of high-proportion Saudi-fly-ash-based concrete
(Peer reviewed; Journal article, 2020)Approximately 544 million tonnes of fly ash (FA) are generated annually worldwide, 80% of which is disposed of in landfills. Thus, using FA as a replacement for cement has turned out to be popular in construction industries ... -
Effect of Stockbridge Dampers on the Vibration Response of Suspension Bridge Hangers
(Master thesis, 2022)Vibrasjoner i hengestengene på Hålogalandsbrua forårsaket av virvelavløsning ble observert under byggingen av broen. Vibrasjonsdempere ble installert for å redusere amplituden til vibrasjonene, men flere av demperne ble ... -
Assembly graphene platelets for bioinspired, stimuli-responsive, low ice adhesion surfaces
(Peer reviewed; Journal article, 2022)Design and fabrication of functional materials for anti-icing and de-icing attract great attention from both academic research and industry. Among them, the study of fish-scale-like material has been proved that enabling ... -
Value of information of in-situ inspections of mooring lines
(Peer reviewed; Journal article, 2021)Mooring systems that are used to secure position keeping of floating offshore oil and gas facilities are subject to deterioration processes, such as pitting corrosion and fatigue crack growth. Past investigations show that ... -
Thermal transport in silver-coated polymer sphere composites by the bidirectional 3ω method
(Peer reviewed; Journal article, 2022)The bidirectional 3ω method is an electrothermal technique that is commonly used to obtain the thermal conductivity of materials such as liquids, biological samples and pastes. In this work, an epoxy-based adhesive was ... -
Dynamisk trykkapasitet i treverk og årringsbreddens betydning for materialegenskapene
(Master thesis, 2022)Denne studien ser nærmere på trykkapsitet parallelt med fiberretningen i treverk under dynamiske tøyningshastigheter, samt årringsbreddens betydning for materialegenskaper som elastitetsmodul og trykkapasitet. Tidligere ... -
Konseptuell utvikling og optimalisering av komposittdekker i tre
(Master thesis, 2022)Formålet med denne oppgaven har vært å optimalisere et dekkeelement av tre som har konkurransedyktige egenskaper sammenlignet med hulldekker av betong. Dekket skulle optimaliseres for CO2-utslipp gjennom materialvalg og ...
