Impact behaviour of stiffened steel plates
(Master thesis, 2015)The impact behavior of stiffened steel plates subjected to impact loading from concentrated loads was studied experimentally and numerically. Both dynamic and quasi-static tests of stiffened steel plates with geometry ... -
Impact Loading on Parts made of Injection-moulded PP
(Master thesis, 2015)This project is set as a part of the ongoing development of the constitutive model the SIMLab Polymer Model (SPM) developed at SIMLab, NTNU. The goal with this thesis is to explore the capabilities of this model using two ... -
Impact of Accelerated Carbonation on Microstructure and Phase Assemblage
(Journal article; Peer reviewed, 2018)The paper summarizes preliminary results on characterization of the microstructure and phase assemblage of mortar and concrete samples containing Portland and Portland -fly ash cement carbonated at ... -
Impact of baseline coronary flow and its distribution on Fractional Flow Reserve prediction
(Journal article; Peer reviewed, 2019)Model‐based prediction of fractional flow reserve (FFR) in the context of stable coronary artery disease (CAD) diagnosis requires a number of modelling assumptions. One of these assumptions is the definition of a baseline ... -
Impact of cracks on distribution of chloride-induced reinforcement corrosion
(Peer reviewed; Journal article, 2023)Surface crack width is regulated in codes to limit corrosion of reinforcement bars in concrete. However, the influence of surface crack width on corrosion damages is not directly inferable from previous research.In this ... -
The impact of curing temperatures on Portland composite cements – hydrate assemblage, porosity, and compressive strength
(Doctoral theses at NTNU;2022:374, Doctoral thesis, 2022)Cement production stands for approx. 8% of the man-made CO2 emissions. One of the most common ways to reduce CO2 emissions in cement production is by replacing part of the clinker with supplementary cementitious materials ... -
Impact of electrodialytic remediation of MSWI fly ash on hydration and mechanical properties of blends with Portland cement
(Peer reviewed; Journal article, 2021)Municipal solid waste incineration (MSWI) residues such as fly ash and air pollution control (APC) residues may serve as new supplementary cementitious materials (SCM). These SCMs may, however, require a pre-treatment to ... -
Impact of Hydrodynamic Interaction Between Pontoons on Global Responses of a Long Floating Bridge Under Wind Waves
(Chapter, 2018)The hydrodynamic interaction between floating bridge pontoons and its impact on the bridge global responses are investigated in the current study. The global model for end-anchored floating bridge for Bjørnefjord crossing ... -
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 ... -
Impact of leaching on chloride ingress profiles in concrete
(Peer reviewed; Journal article, 2022)To investigate the effect of leaching on chloride ingress profiles in concrete and mortar, we exposed concrete and mortar specimens for 90 and 180 days to two different exposure solutions: 3% NaCl, and 3% NaCl with KOH ... -
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 ... -
Impact of sample crushing on porosity characterization of hardened cement pastes by low temperature calorimetry: Comparison of powder and cylinder samples
(Journal article; Peer reviewed, 2018)Impact of sample crushing on porosity characterization of hardened cement pastes by low temperature calorimetry: Comparison of powder and cylinder samples -
Impact of stress triaxiality, strain rate, and temperature on the mechanical response and morphology of PVDF
(Journal article; Peer reviewed, 2022) -
Impact of super absorbent polymers on early age behavior of high performance concrete walls
(Chapter, 2021)The prediction of the early age behavior of cementitious materials is a difficult task, because many of the material properties are very sensitive to curing conditions as it is the case for High Performance Concrete (HPC), ... -
Impact on Duplex Stainless Steel Pipes with and without Precipitated Sigma phase
(Master thesis, 2010)A manufacturing defect in pipe fittings supplied to the oil and gas industry has resulted in installed components with unknown impact capacity. If the altered capacity is not sufficient, production stops and expensive ... -
Impact on Duplex Steel Pipes with Precipitated Sigma-phase: Modeling a Full-scale Impact Test on Pipe Fittings
(Master thesis, 2012)Duplex stainless steel (DSS) is a common material in offshore pipe fittings. A manufacturing defect has altered the behavior of the components through an erroneous heat treatment, which has led to precipitation of 𝜎-phase. ... -

Implementation of a non-linear foundation model for soil-structure interaction analysis of offshore wind turbines in FAST
(Journal article; Peer reviewed, 2017)Bottom-fixed offshore wind turbines (OWTs) involve a wide range of engineering fields. Of these, modelling of foundation flexibility has been given little priority. This paper investigates the modelling of bottom-fixed ...
