(Peer reviewed; Journal article, 2020)The design, construction, and operation of civil infrastructure that is more environmentally, socially, and economically responsible over its life cycle from extraction of raw materials to end of life is increasingly ... -
Impact of leaching on chloride ingress profiles in concrete
(Master thesis, 2019)Kloridinitiert armeringskorrosjon er en av hovednedbrytningsmekanismene for armerte betongkonstruksjoner. Klorider trenger igjennom betongoverdekningen over tid og forårsaker korrosjon når de når et kritisk kloridinnhold ... -
Probability-based assessment of the Stavå bridge
(Master thesis, 2020)Denne masteroppgaven handler om beslutningsprosessen angående hva man skal gjøre med Stavåbrua. Hovedmålet med oppgaven er å finne ut hva man skal gjøre med Stavåbrua. Oppgaven tar ikke bare for seg på de rene konstrukjo ... -
Effects of Morphology and Temperature on the Tensile Characteristics of Carbon Nitride Nanothreads
(Journal article; Peer reviewed, 2020)Very recently synthesized carbon nitride nanothreads (CNNTs) by compressing crystalline pyridine show outperformance in chemical and physical properties over diamond nanothreads. Here, using first-principle based ReaxFF ... -
On the study of the effect of Luders plateau on fracture response with cohesive zone model
(Peer reviewed; Journal article, 2019)For materials presenting Lüders plateau, low temperatures in the Arctic region will prolong the plateau length. In this study, the effect of Lüders plateau on crack growth resistance has been investigated with cohesive ... -
Enhancement of Thermal Boundary Conductance of Metal–Polymer System
(Peer reviewed; Journal article, 2020)In organic electronics, thermal management is a challenge, as most organic materials conduct heat poorly. As these devices become smaller, thermal transport is increasingly limited by organic–inorganic interfaces, for ... -
Supergiant elasticity and fracture of 3D spirally wound MoS2
(Peer reviewed; Journal article, 2020)Recently experimentally synthesized three-dimensional (3D) MoS2 spiral is a new kind of helical structure with technically robust properties. Among them, the mechanical properties of such appealing materials are indispensable ... -
ALE-VMS methods for wind-resistant design of long-span bridges
(Peer reviewed; Journal article, 2019)For unsteady aerodynamics, the Arbitrary Lagrangian-Eulerian Variational Multi-Scale (ALE-VMS) formulation for incompressible flows has proven an accurate and powerful method. In this paper we present an overview of some ... -
Wind Field Variability in Complex Terrain: Lessons from the Hardanger Bridge
(Chapter; Peer reviewed, 2019)Along the Coastal Highway E39 in the western coast of Norway, Norwegian Government is planning to build several extreme bridges spanning from 1.5 to 5 km. The region is typically mountainous with deep fjords seeping inland. ... -
CO2 Wetting on Pillar-Nanostructured Substrates
(Peer reviewed; Journal article, 2020)CO2 capture by dropwise CO2 condensation on cold solid surfaces is a promising technology. Understanding the role of the nanoscale surface and topographical features of CO2 droplet wetting characteristics is of importance ... -
Rate dependent fracture of monolithic and laminated glass: Experiments and simulations
(Peer reviewed; Journal article, 2020)Glass is a brittle material known to possess large scatter in its fracture strength, which is caused by the existence of microscopic surface flaws. Fracture in glass generally originates from stress concentrations around ... -
The Effect of Thermal Residual Stresses on Ductile-to-Brittle Transition of a Welded TMCR Steel by Using CAFE Method
(Peer reviewed; Journal article, 2019)The effect of residual stress on fracture of materials or structures has been widely studied. However, its influence on ductile-to-brittle transition (DBT), a crucial phenomenon of structural materials, has rarely been ... -
Screening of untreated municipal solid waste incineration fly ash for use in cement-based materials: chemical and physical properties
(Peer reviewed; Journal article, 2020)The environmental impact during concrete manufacturing can be reduced by using less cement or using types of cement with high amounts of secondary cementitious materials (SCMs) and fillers. Fly ash from municipal solid ... -
Nanoscale Correlations of Ice Adhesion Strength and Water Contact Angle
(Peer reviewed; Journal article, 2020)Surfaces with low ice adhesion represent a promising strategy to achieve passive anti-icing performance. However, as a successful and robust low ice adhesion surface must be tested under realistic conditions at low ... -

Aerodynamic Effect of Non-uniform Wind Profiles for Long-Span Bridges
(Chapter, 2019)Long-span bridges are often designed based on the assumption of wind field homogeneity. At the Hardanger Bridge, the wind field along the bridge span is monitored though 8 triaxial ultrasonic anemometers. Simultaneously ... -
Damage Detection Applied to a Full-Scale Steel Bridge Using Temporal Momens
(Peer reviewed; Journal article, 2020)The most common damages in existing highway and railway steel bridges are related to fatigue and are, as reported in the literature, found in the structural system of the bridge deck. This paper proposes a methodology for ... -
Fundamental Mechanisms of Ice Adhesion
(Doctoral theses at NTNU;2020:87, Doctoral thesis, 2020)Uønsket isdannelse skaper bade daglige problemer og farlige situasjoner hvert år. Heldigvis er det måter å hindre slik uønsket ising. Overflater med lav isvedheft, der isen sklir rett av overflaten, er en lovende metode ... -
Effect of foundation type and modelling on dynamic response and fatigue of offshore wind turbines
(Peer reviewed; Journal article, 2019)This paper presents dynamic response and fatigue analyses of several bottom-mounted offshore wind turbine (OWT) models, simulated in the aero-hydro-servo-elastic simulation tool FAST. The distinction between the models is ... -
