Fracture assessment of V-notched specimens with end holes made of tungsten-copper functionally graded material under mode I loading
(Journal article; Peer reviewed, 2018)The present research is the first to assess fracture of V-notches with end holes (VO-notches) made of tungsten-copper functionally graded material (W-Cu FGM) under mode I both experimentally and theoretically. W-Cu FGM ... -
Fracture behaviour of notched as-built EBM parts: Characterization and interplay between defects and notch strengthening behaviour
(Journal article, 2018)Additive manufacturing (AM) offers the potential to economically produce customized components with complex geometries. However, the introduction of complex geometry goes hand in hand with the presence of notches. Thus, ... -
Fracture resistance of 3D nano-architected lattice materials
(Journal article, 2022)Exploiting small scale material effects and structural topology, nano-architected lattices represent a recent novel class of mechanical metamaterials, which exhibit unprecedented combination of mechanical properties. ... -
Fracture toughness and hydrogen embrittlement susceptibility on the interface of clad steel pipes with and without a Ni-interlayer
(Journal article, 2017)The objective of the present work has been to study the fracture properties of the interface between clad and base material of two 316 L austenitic stainless steel - X60/X65 carbon steel hot roll bonded clad pipes; with ... -
Fragments Generated during Liquid Hydrogen Tank Explosions
(Peer reviewed; Journal article, 2023)Liquid hydrogen (LH2) may be employed to transport large quantities of pure hydrogen or be stored onboard of ships, airplanes and trains fuelled by hydrogen, thanks to its high density compared to gaseous compressed hydrogen. ... -
FRAM Approach for Barrier Management in Offshore Drilling
(Chapter, 2020)Accident investigations in offshore oil and gas industry indicate that inadequate barrier management has been one of the main causes of many offshore accidents. Event trees commonly have been used for safety barrier risk ... -
Framework for Discussing Sustainability Improvement in Container Ports – a Nordic Case Study
(Doctoral thesis at NTNU;2016:178, Doctoral thesis, 2016)This PhD research project proposes a five-construct framework for discussing how to improve the sustainability performance in Nordic container ports (NCPs). The port of Narvik is used as a representative case study whenever ... -
Framework for Layout Design Supporting Patient Flow in Outpatient Departments
(Master thesis, 2018)In the last decades, there has been an increase in demand for outpatient services, as inpatient treatments are more often done on an outpatient basis. Increase in demand, and long waiting times in the access of outpatient ... -

(Master thesis, 2018)Mosjøen havn IKS ønsker å styrke sin posisjon som terminalaktør for intermodale logistikk løsninger i egen region ved å løse ut potensialer for økt jernbane- og sjøtransport til og fra lokale næringslivsaktører. Oppgaven ... -
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 ... -
