Local bracer vibrations for Offshore Wind jackets
(Master thesis, 2013)During the course of this master project, the candidates have worked with FEA of local vibrations occurring in bracers on offshore windturbine jacket. These vibrations arise as a dynamic response from wind-, wave-, and ... -
Local Dynamics of Offshore Wind Turbine Jacket Sub-structures
(Master thesis, 2010)The scope of this thesis has been to investigate the existence of out-of-plane vibration of jacket sub-structures for offshore wind turbines. This is done by making the program code JAC (Jacket Analysis Code), which is ... -
Local electrical properties of thermally grown oxide films formed on duplex stainless steel surfaces
(Journal article, 2018)The local electrical properties of thermally grown oxide films formed on ferrite and austenite surfaces of duplex stainless steel at different temperatures were investigated by Current sensing atomic force microscopy, X-ray ... -
Local entropy generation and entropy fluxes of a transient flame during head-on quenching towards solid and hydrogen-permeable porous walls
(Peer reviewed; Journal article, 2021)Premixed H2-air flames are studied in a one-dimensional wall-bounded configuration. The laminar flame propagates towards and quenches at a wall that is either solid or permeable. Entropy generation by each of 19 elementary ... -
Local Heating Networks with Waste Heat Utilization: Low or Medium Temperature Supply?
(Peer reviewed; Journal article, 2020)District heating enables an economical use of energy sources that would otherwise be wasted to cover the heating demands of buildings in urban areas. For efficient utilization of local waste heat and renewable heat sources, ... -
Local ionospheric modelling of GPS code and carrier phase observations
(Peer reviewed; Journal article, 2008)A limiting factor for successful ambiguity resolution in precise GPS positioning is the existence of un-modelled ionospheric errors in both the carrier phase and the pseudorange measurements. In this study, the ionospheric ... -
Local loss coefficients inside air cavity of ventilated pitched roofs
(Journal article; Peer reviewed, 2018)Pitched roofs with a ventilated air cavity to avoid snow melt and ensure dry conditions beneath the roofing are a widely used construction in northern parts of Europe and America. The purpose of this study has been to ... -
Local mechanical properties and precipitation inhomogeneity in large-grained Al–Mg–Si alloy
(Peer reviewed; Journal article, 2022)Al–Mg–Si (6xxx series) alloys show excellent mechanical properties due to the precipitates formed during heat treatment. However, heat treatment of these alloys results in a soft precipitation free zone (PFZ) close to grain ... -
Local Ocean Wave Field Estimation Using A Deep Generative Model of Wave Buoys
(Journal article, 2023)Estimating oceanic wave fields from sparse observations has been a long-standing challenge in oceanography and an important environmental metric desired for maritime operations. The requirement for frequent real-time updates ... -
Local soil classification and assessment of the mechanical properties with emphasis on pile adfreeze bond strength in Longyearbyen, Svalbard
(Master thesis, 2022)Construction engineering practices have been a highly sensitive topic regarding the Arctic infrastructure. The limitations of the permafrost behavior impose an analysis from the thermal and mechanical point of view. The ... -
Local strain energy based fatigue assessment of cruciform welded joints: experimental data analysis and influence of hot-dip galvanization
(Journal article; Peer reviewed, 2018)Performing the fatigue assessment of a welded joint using the Notch Stress Intensity Factors [1] presents two major challenges. The first is the necessity of a precise reconstruction of the stress field around the notch ... -
Local strain energy density for the fatigue assessment of hot dip galvanized welded joints: Some recent outcomes
(Journal article; Peer reviewed, 2017)Since in literature only data about the effect of the hot-dip galvanizing coating on fatigue behavior of unnotched specimens are available, whereas very few for notched components and none for welded joints, the aim of ... -
Local strain energy density for the fracture assessment of polyurethane specimens weakened by notches of different shape
(Journal article; Peer reviewed, 2017)Recent studies on local stress fields in proximity of crack and notch tips have shown that Strain Energy Density (SED), averaged in a circular control volume surrounding the point of stress singularities, represents a ... -
Local strain energy density to assess the multiaxial fatigue strength of titanium alloys
(Peer reviewed; Journal article, 2016)The present paper investigates the multiaxial fatigue strength of sharp V-notched components made of titanium grade 5 alloy (Ti-6Al-4V). Axisymmetric notched specimens have been tested under combined tension and torsion ... -
Local Structural Analysis of a Semi-Submersible Exposed to Ice Loads
(Master thesis, 2015)The subject of deep sea drilling in the Arctic is now more relevant than ever. The environment in Arctic offshore areas can be extremely harsh and the structures operating there will have to be designed accordingly. In ... -
Local thermodynamic description of isothermal single-phase flow in porous media
