Francis-99: Evaluation of the strain energy density value for welded joints typical of turbine runner blades
(Journal article; Peer reviewed, 2019)The main aim of this work is to investigate the fatigue behaviour of welded joints through an energetic approach based on the Strain Energy Density failure criteria. The geometries, taken from the literature, are typical ... -
Fremtidens vedlikeholdsstyring av trommelmotorer ved SalMar AS
(Master thesis, 2017)Norsk oppdrettsnæring har i løpet av de siste tiår vært preget av stor vekst og utgjør p.t. ca. 70 % av Norges sjømateksport. SalMar ASA er i dag verdens tredje største oppdrettsselskap med et volum oppdrettslaks i sjøen, ... -
FRICTION AND WEAR OF COATINGS FOR SUBSEA GATE VALVES OPERATING AT HIGH TEMPERATURE AND PRESSURE
(Doctoral thesis at NTNU;2016:161, Doctoral thesis, 2016)Gate valves for subsea oil and gas operation work under harsh conditions. Proper design ensures the valves functional integrity over the designed lifetime of the valve. The design of the valve includes material choice ... -
Friction Fluctuations of Gold Nanoparticles in the Superlubric Regime
(Journal article; Peer reviewed, 2018)Superlubricity, or alternatively termed structural (super)lubrictiy, is a concept where ultra-low friction is expected at the interface between sliding surfaces if these surfaces are incommensurate and thus unable to ... -
Friction Mechanisms by Carboxylic Acids in Aqueous Lubricants
(Journal article; Peer reviewed, 2018)Carboxylic acids are well known for their friction-reducing abilities driven by the formation of low-shear-strength films on the steel surface. However, understanding of the adsorption mechanisms especially in polar solvents ... -
Friction stir welding/processing of mg-based alloys: A critical review on advancements and challenges
(Peer reviewed; Journal article, 2021)Friction stir welding (FSW) and friction stir processing (FSP) are two of the most widely used solid-state welding techniques for magnesium (Mg) and magnesium alloys. Mg-based alloys are widely used in the railway, aerospace, ... -
Friction vs. Area Scaling of Superlubric NaCl-Particles on Graphite
(Journal article; Peer reviewed, 2019)Structural lubricity is an intriguing tribological concept, where extremely low friction is anticipated, if two surfaces in relative motion do not share the same lattice structure and consequently instabilities originating ... -
From CAD-Assemblies to Constraint Based Robot Control
(Master thesis, 2019)Denne masteroppgaven har som mål å finne ut om det er mulig å programmere en robot utelukkende med informasjon tilgjengelig i 3D-design software (CAD). Mer spesifikt, hvordan dette programmet kan bli implementert på en ... -
From captain to button-presser: operators’ perspectives on navigating highly automated ferries
(Journal article; Peer reviewed, 2022)Teaming with Artificial Intelligence (AI) is changing the way seafarers work. We show that a new kind of seafaring is emerging, characterized by cooperation with AI systems. In this format of seafaring, navigation tasks ... -
From Copper to Composite Stator - Early Phase Product Development of Fiber Printing Techniques
(Master thesis, 2018)Key insights from the making of two stators, and two complete electric motors, have laid the foundations for an improved production machinery based on the patent of Alva Motor Solutions. As resources are limited, an iterative ... -
