Enabling Sequential Rupture for Lowering Atomistic Ice Adhesion
(Journal article; Peer reviewed, 2019)State-of-the-art passive icephobicity relies mainly on static parameters such as surface energy, coating elastic modulus, crack sizes and so on. Low ice adhesion resulting from dynamic de-icing process, for instance ice ... -
Efficient Liquefaction of Carbon Dioxide on Superlyophobic Surfaces
(Journal article, 2019)Liquefaction of CO2 is a necessary step in several parts of the carbon capture, transport and storage (CCS) chain, e.g. for processing for ship transport. By increasing the efficiency of condensation, a lower energy ... -
Impact of production parameters on physiochemical characteristics of wood ash for possible utilisation in cement-based materials
(Journal article; Peer reviewed, 2019)Energy production is reorganised to mitigate the pressure on the global environment. This reorganisation leads to an increase in the production of wood ash (WA). Multivariate modelling was used to identify the link between ... -
Comparing In Situ DIC Results from an Etched Surface with a Gold Speckled Surface
(Journal article; Peer reviewed, 2019)A ferrite-pearlite two-phase steel was investigated using in situ scanning electron microscope (SEM) tensile testing combined with digital image correlation (DIC). Two different speckled patterns were used and compared. ... -
Drive-by scour monitoring of railway bridges using a wavelet-based approach
(Journal article; Peer reviewed, 2019)This paper numerically investigates the feasibility of using bogie acceleration measurements from a passing train to detect the presence of bridge scour. The Continuous Wavelet Transform is used to process the simulated ... -
Transportation of Janus Nanoparticles in Confined Nanochannels: A Molecular Dynamics Simulations
(Journal article; Peer reviewed, 2019)Janus nanoparticles (NP) have drawn great attention due to their unique surface of dual characters. In this study, transportation of Janus NPs contained two-phase fluids in an ultra-confined channel was studied by molecular ... -
Breathable Nanowood Biofilms as Guiding Layer for Green On‐Skin Electronics
(Journal article; Peer reviewed, 2019)Thin‐film electronics are urged to be directly laminated onto human skin for reliable, sensitive biosensing together with feedback transdermal therapy, their self‐power supply using the thermoelectric and moisture‐induced‐electric ... -
Consistent crack width calculation methods for reinforced concrete elements subjected to 1D and 2D stress states A mixed experimental, numerical and analytical approach
(Doctoral theses at NTNU;2019:147, Doctoral thesis, 2019)Predicting crack widths in reinforced concrete (RC) structures is important for Serviceability Limit State (SLS) design. Crack widths exceeding the requirements can impair the functionality of a structure, limit its use ... -
Clays as SCM – Reactivity of Uncalcined Kaolinite and Bentonite, and Impact on Phase Assemblage and Strength Development of PC Mortars
(Journal article; Peer reviewed, 2019)The impact of substitution of cement paste with uncalcined clay (bentonite and kaolinite) in the range of 5% by volume of paste on the development of hydration and properties of mortar was investigated. Two issues were ... -
Recommended practice for reporting experimental data produced from studies on corrosion of steel in cementitious systems
(Journal article; Peer reviewed, 2019)Experience has shown that many aspects of experimental design for studying steel corrosion in cementitious systems may significantly influence the obtained results. In the absence of standardized methods to study steel ... -
Topography studies of concrete abraded with ice
(Journal article; Peer reviewed, 2019)Topography studies of concrete-ice abrasion were made to proceed in our understanding of the mechanisms of concrete wear by ice on Arctic offshore structures. The effects on various initial surfaces of a B75 normal-weight ... -
Fragility of transport assets exposed to multiple hazards: State-of-the-art review toward infrastructural resilience
(Journal article; Peer reviewed, 2019)Vulnerability is a fundamental component of risk and its understanding is important for characterising the reliability of infrastructure assets and systems and for mitigating risks. The vulnerability analysis of infrastructure ... -
Buckling initiation in layered hydrogels during transient swelling
(Journal article; Peer reviewed, 2019)Subjected to compressive stresses, soft polymers with stiffness gradients can display various buckling patterns. These compressive stresses can have different origins, like mechanical forces, temperature changes, or, for ... -
Load model of historic traffic for fatigue life estimation of Norwegian railway bridges
(Doctoral theses at NTNU;2019:73, Doctoral thesis, 2019)Material fatigue is the primary damage mechanism in steel railway bridges and ultimately causes material fracture and eventually component and system failure. It is essential that the infrastructure owner can predict and ... -
Seismic considerations in design of offshore wind turbines
(Journal article; Peer reviewed, 2018)Interest in renewable and clean energy over the past decade has motivated immense research on wind energy. The main issues in design of offshore wind turbines in regions of recent development have been aero- and hydro-dynamic ... -
Effect of different microstructural features on the hydrogen embrittlement susceptibility of alloy 718
(Journal article; Peer reviewed, 2018)Due to its high strength and acceptable corrosion resistance, Alloy 718 is a viable material for the use in subsea applications. The alloy's susceptibility to hydrogen embrittlement is however limiting its viability. In ... -
Hydrogen-microvoid interactions at continuum scale
(Journal article; Peer reviewed, 2018)Experimentally, it has been shown that hydrogen can either enhance the internal necking failure or induce internal shearing failure of microvoids. In this study, the numerical investigation of hydrogen-microvoid interactions ... -
Liquid layer generator for excellent icephobicity at extremely low temperature
(Journal article; Peer reviewed, 2019)Progress in icephobicity has been made in recent years. However, the majority of the icephobic surfaces reported are relying on mechanisms of static nature, and maintaining low ice adhesion of these surfaces at extreme ... -
Environmentally assisted degradation of spinodal copper alloy C72900
(Journal article; Peer reviewed, 2018)In this work, a spinodal Copper alloy – C72900, was tested to investigate the resistance against environmentally assisted degradation. The material was tested according to ISO 15156-3 Level V in sour H2S solution and to ... -
Hydrogen stress cracking and crack initiation in precipitation hardened Ni-alloys
(Journal article; Peer reviewed, 2018)The two different precipitation hardened nickel alloys, Alloy 718 and Alloy 725, were tested in its as received condition. Their susceptibility to hydrogen stress cracking was examined by the use of stepwise increasing ...
