Effect of low temperature tensile properties on crack driving force for Arctic applications
(Journal article; Peer reviewed, 2017)Many petroleum companies expand their activities further north towards the Arctic region, resulting in design temperatures down to −60 °C, which is much lower than what is usual for most current petroleum installations. ... -
Effect of materials on sedimentation of cement paste
(Chapter; Peer reviewed, 2013)A conceptual model for the stability of paste was proposed and an experimental system, HYdroStatic Pressure Test (HYSPT), was developed for detecting the sedimentation of fresh cement paste. By accurate measurements of the ... -
Effect of Nanoparticles on Spontaneous Imbibition of Water into Ultraconfined Reservoir Capillary by Molecular Dynamics Simulation
(Journal article; Peer reviewed, 2017)Imbibition is one of the key phenomena underlying processes such as oil recovery and others. In this paper, the influence of nanoparticles on spontaneous water imbibition into ultraconfined channels is investigated by ... -
Effect of Non-spherical Voids on the Mechanical Behavior of Shape Memory Alloys
(Master thesis, 2013)The use of shape memory alloys has seen a steady increase since its discovery.Understanding the mechanical behavior behind a ductile fracture of these materialsis important to further the applicability of shape memory ... -

The effect of plastic deformation on hydrogen diffusion in nickel Alloy 625
(Peer reviewed; Journal article, 2022)Recently, several hydrogen-assisted failures have been reported on different nickel alloys used in the subsea oil and gas industries. It is thus essential to correlate hydrogen uptake and diffusion behavior with stress ... -
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 ... -
Effect of rod-to-grain angle on capacity and stiffness of axially and laterally loaded long threaded rods in timber joints
(Journal article; Peer reviewed, 2018)Long threaded rods have recently been widely used as a reinforcement of glued laminated timber in perpendicular to the grain direction. The recent research has thus focused mainly on the withdrawal properties of the threaded ... -
Effect of Set Accelerator on Capillary Suction and Porosity of Concrete – Cast Samples with Constant Water/Binder Ratio
(Peer reviewed; Journal article, 2022)Alkali-free set accelerators are added at the nozzle to ensure rapid set of wet sprayed concrete. The accelerator affects the strength development, porosity and transport properties, and hence the durability, of the sprayed ... -
Effect of Set Accelerator on Properties of Wet Sprayed Concrete
(Peer reviewed; Journal article, 2022)This paper describes sprayed concrete experiments varying the set accelerator dose. Literature on the hydration of cement with modern alkali-free set accelerators is reviewed and two full scale wet spraying experiments ... -
The effect of shrinkage reducing admixtures on drying shrinkage, autogenous deformation, and early age stress development of concrete
(Peer reviewed; Journal article, 2021)The current study investigates the effect of shrinkage reducing admixtures (SRA) on volume changes that may lead to shrinkage cracking and early age cracking. Drying shrinkage (DS) and autogenous deformation (AD), the ... -
Effect of side branch flow upon physiological indices in coronary artery disease
(Peer reviewed; Journal article, 2020)Recent efforts have demonstrated the ability of computational models to predict fractional flow reserve from coronary artery imaging without the need for invasive instrumentation. However, these models include only larger ... -
Effect of silica fume, steel fiber and ITZ on the strength and fracture behavior of mortar
(Journal article; Peer reviewed, 2010)Two sets of parameters known to affect the quality and thickness of the interfacial transition zone (ITZ), i.e. water/binder ratio and content of silica fume were varied in a series of mortars without and with steel fiber. ... -
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 ... -
Effect of spatial variation and possible interference of localised corrosion on the residual capacity of a reinforced concrete beam
(Doctoral thesis at NTNU;2015:282, Doctoral thesis, 2015)While much numerical and experimental work has progressed to assess the structural performance of corrosion damaged RC beams, there is to the authors’ knowledge no work on numerical analysis considering spatial variation ... -
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 ... -
Effect of temperature curing on properties and hydration of wollastonite blended magnesium potassium phosphate cements
(Peer reviewed; Journal article, 2021)K-struvite, the main hydrate of magnesium potassium phosphate (MKP) cements, dehydrates at ~50 °C, thus elevated temperatures at service conditions could affect cement properties and durability. In this study, properties ... -
