Formation of Built-Up Layer on the Tool in Turning Operation of Magnesium Alloys
(Journal article; Peer reviewed, 2018)The present work highlights some factors which affect formation of a protective built-up layer (BUL) on the rake face of the cutting tool when cutting magnesium alloys. This work suggests that BUL can positively affect ... -
Formation of fully equiaxed grain microstructure in additively manufactured AlCoCrFeNiTi0.5 high entropy alloy
(Journal article; Peer reviewed, 2019)In this work, the non-equiatomic high entropy alloy AlCoCrFeNiTi0.5 was additively manufactured via the laser engineered net shaping (LENS™) process. Contrary to the columnar grain microstructure commonly observed in ... -
Formulation and Testing of New Environmentally Acceptable Lubricants (EAL) for Use in Maritime Gear Components
(Master thesis, 2019)I marin industri er lekkasje av smøremidler en stor miljøutfordring. For å redusere slik forurensning til sjøvannet må alle fartøy benytte miljøvennlige smøremidler i all olje til sjø grensesnitt. I disse grensesnittene ... -
Formulation of Enhanced Water-Glycol Lubricants for Offshore Components - The Influence of Thickeners in Environmentally Acceptable Lubricants on the Wear of a Steel Piston Cylinder
(Master thesis, 2016)The service life of offshore stainless steel cylinders used for riser tensioner systems is lower than expected. This is due to the complex degradation mechanisms, like corrosion, wear and fatigue, that take place under the ... -
Forslag til gjennomføringsmodell for kommunale vann- og avløpsprosjekter
(Master thesis, 2021)Vannbransjen tjener et viktig formål i samfunnet gjennom leveranser av vann- og avløpstjenester. For å møte befolkningsveksten, innfri stadig strengere kvalitets- og reguleringskrav og ta igjen etterslepet i infrastrukturen, ... -
Forslag til RCA-metodikk tilpasset vindparker
(Bachelor thesis, 2020)Dette er en oppgave skrevet med formål om å foreslå en RCA-metodikk for til bruk på Trønderenergi sine vindparker. Trønderenergi vil innføre RCA i sitt vedlikeholdssystem for å gjøre vedlikeholdet på deres vindmøller mer ... -
Forsyning av ferskvarer til matvarebutikker - En løsning for en automatisk vareforsyning
(Master thesis, 2015)Tilgang på mat er en livsnødvendighet for mennesker og god styring av verdikjeden fra matproduksjon til butikk er viktig for at vi skal ha tilgang på sunne, friske og trygge matvarer. Matvareindustrien spiller en viktig ... -
Forurensninger i overvann og datasimuleringer av first flush - Modellering av forurensningskonsentrasjoner i overvann gjennom en nedbørshendelse
(Master thesis, 2015)Sammenlignet med spillvann, ses gjerne overvann på som relativt rent. Ved separering av ledningsnett kan derfor overvann noen ganger slippes urenset ut i resipienten. Det er likevel slik at overvann inneholder en rekke ... -
Foundations of risk assessment
(Master thesis, 2010)The purpose of this study is to shed light on the foundations of risk assessment. By exploring the polysemantics of basic concepts and their influence on the process and results of risk assessment, the thesis endeavors to ... -
Fractographic features of technically pure magnesium, AZ31 and ZK60 alloys subjected to stress corrosion cracking
(Peer reviewed; Journal article, 2020)Using quantitative fractography, the present study clarifies the effect of chemical composition and preliminary plastic deformation on the fracture mode of structural magnesium alloys experienced stress corrosion cracking ... -
Fracture analysis of V‐notched rubbers: An experimental and theoretical study
(Journal article, 2018)In this study, the rupture load in rubbers weakened by sharp V‐notch is investigated under mode I loading. To this end, first, mode I fracture tests are performed on V‐notched samples made of styrene‐butadiene rubbers and ... -
