Kirchhoff-Love shells within strain gradient elasticity: weak and strong formulations and an H3-conforming isogeometric implementation
(Journal article; Peer reviewed, 2018)A strain gradient elasticity model for shells of arbitrary geometry is derived for the first time. The Kirchhoff–Love shell kinematics is employed in the context of a one-parameter modification of Mindlin’s strain gradient ... -
Kombinert modelbasert og sensorbasert observer for undervannsfartøy
(Master thesis, 2014)Denne master-oppgaven omhandler arbeidet med å kombinere to ulike typer observere på en slik måte at kombinasjonen av disse to gir et bedre resultat enn det de to observerene klarer hver for seg. De to observerene er den ... -
Kombinert Wind- og Bølgekraft
(Master thesis, 2015)I denne master oppgaven ble muligheten for å kombinere vind- og bølgekraft undersøkt. Det er blitt utført et litteraturstudie på ulike konsepter av vindkraft, bølgekraft og kombinert vind- og bølgekraft. Basert på den ... -
Kon-Tiki2 Expedition 2015-2016 Scientific Cruise Report
(Research report, 2017)The Kon-Tiki2 Expedition was partly an anthropogenic exploration and partly an interdisciplinary oceanic and atmospheric research expedition. As a research expedition it was unique for three reasons: 1) The type of vessel ... -
Konsekvensklassifisering og FMECA av fôrflåte
(Bachelor thesis, 2023)Formålet med oppgaven var å identifisere sviktmoder på ett av Mowi sine anlegg, for videre å finne relevante tilstandsparametere. På bakgrunn av dette var det ønskelig at gruppen skulle komme med forslag til kriterier for ... -
Konseptutvikling av en offshore supply base plassert i Barentshavet
(Master thesis, 2013)Den globale etterspørselen etter petroleum er økende, og produksjon av olje-og gassressurser flyttes til stadig nye lokasjoner. Dette har ført til et økt fokus på mulighetene for å utvinne petroleum i nordområdene, også i ... -
Laboratory experiments on shared-energy collisions between freshwater ice blocks and a floating steel structure
(Journal article; Peer reviewed, 2017)Ship collisions with floating ice in which the ship sustains damage are in the shared-energy regime – both the ice and the ship dissipate energy through inelastic deformations. The physics of these events are rarely studied. ... -
Large Eddy Simulations of flow around a circular cylinder close to a flat seabed
(Journal article, 2016)Large Eddy Simulations (LES) with Smagorinsky subgrid scale model are used to study the turbulent flow and wake dynamics behind a circular cylinder close to a horizontal, plane wall at subcritical Reynolds number. The focus ... -
