Forslag til vedlikeholdsprogram og design av oppbevarings- og fordelingssystemer for hydrogengasstanker
(Bachelor thesis, 2024)Bachelorgruppen har utarbeidet et forslag til et vedlikeholdsprogram for Hexagon Purus Maritimes sine nye oppbevarings- og fordelingssystemer av komprimert hydrogengasstanker. Det har også blitt gjort et tverrfaglig forsøk ... -
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 ... -
Fracture assessment of magnetostrictive materials
(Journal article; Peer reviewed, 2017)Giant magnetostrictive materials are gaining interest in the field of smart material, especially the commercially known Terfenol-D, that is an alloy made out of iron, terbium and dysprosium (Tb0.3Dy0.7Fe1.9). Since these ... -
Fracture assessment of PEEK under static loading by means of the local strain energy density
(Journal article; Peer reviewed, 2017)Polyetheretherketone (PEEK) has gained interest in many industrial applications due to its high strength-to-weight ratio, excellent heat tolerance and high corrosion resistance. Stress concentrators such as notches and ... -
Fracture assessment of polyacrylonitrile nanofiber-reinforced epoxy adhesive
(Journal article, 2018)Electrospun polyacrylonitrile (PAN) nanofibers were incorporated in an epoxy-based adhesive layer to improve the adhesive joint’s mechanical performance. The morphological study of the electrospun PAN nanofibers revealed ... -
Fracture assessment of U-notched graphite specimens by means of cohesive zone model
