Heat dissipation and acoustic emission features of titanium alloys in cyclic deformation mode
(Peer reviewed; Journal article, 2021)The present work unveils the features of heat dissipation and acoustic emission accompanying the fatigue crack growth in a titanium alloy (Ti-0.8Al-0.8Mn and Ti Grade 2) using the compact tension and Charpy V-notch specimens. ... -
Heat Engine for Co-Generating Electric Power Plant
(Master thesis, 2011)Utilization of geothermal energy within the Oil Industry is a topic that the Oil Industry today is aware of but no large scale systems, like the Co-Generation system, has yet been implemented to existing subsea installations. The ... -
Helsefarlig brøyteutstyr
(Bachelor thesis, 2022)Denne oppgaven tar for seg utfordringer presentert av Steinkjer kommune knyttet til brøyting. Når kommunen er ferdig å brøyte fortauene i kommunen, ligger det igjen en glatt overflate som er farlig for fotgjengerne å gå ... -
High cycle fatigue life estimation of AlSi10Mg processed by laser powder bed fusion
(Journal article; Peer reviewed, 2018)Fatigue life is known to be dependent on the surface properties of the material. Surface roughness provokes local stress concentration and cause crack initiation even at minute cyclic loads. In laser powder bed fusion, the ... -
High cycle fatigue life estimation of materials processed by laser powder bed fusion
(Journal article, 2019)The fatigue life of metal components is known to depend on the surface topography. For components made by laser powder bed fusion, the roughness of the as‐built surfaces depends on the orientation of the component surface ... -
High Performance AM Connecting Rod Design and Optimization
(Master thesis, 2019)Hensikten med denne masteroppgaven var å optimalisere og designe et AM høyytelsesråde til Hondas CRF250R motor. Optimaliseringsprosessen ble utført ved bruk av to forskjellige metoder der en av de inkluderte topologioptimalisering ... -
High Performance Engine Design And Optimization
(Master thesis, 2019)I denne master oppgaven er mulighetene for høy ytelses optimalisering av CRF250L mo- toren blitt studert. Ytelse og pa ̊litelighet har blitt forbedret gjennom a ̊ øke motorvolum til 305cm3 og optimalisere interne komponenter. ... -
High Performance Fine-Grained Biodegradable Mg-Zn-Ca Alloys Processed by Severe Plastic Deformation
(Journal article; Peer reviewed, 2019)The tensile strength, fatigue, and corrosion fatigue performance of the magnesium alloy ZX40 benefit strongly from hybrid deformation processing involving warm equal-channel angular pressing (ECAP) at the first step and ... -
High Performance Valve Spring Failure Mode Detection
(Master thesis, 2019)I denne oppgaven blir det undersøkt hvordan ventilmekanismen i en forbrenningsmotor styrer ventilene, og da spesielt med tanke på hvordan kamprofilen og vippearmenes oppsett samvirker for å generere løftkurven for ventilene. ... -
High pressure unlined tunnels: Exemplified with Nye Tyin Hydropower Project
(Master thesis, 2013)Topographic condition in Norway is favorable for the development of hydropower and more than 99% of annual production of energy in Norway is generated from hydropower. Unlined tunnels and underground powerhouses have been ... -
High strength and fatigue properties of Mg-Zn-Ca alloys after severe plastic deformation
(Journal article; Peer reviewed, 2019)Magnesium alloys are the lightest metallic structural materials with an outstanding specific strength. This makes them appealing for a wide range of applications in “green” transportation where weight saving is of major ... -
High-concentration freeform microtracking concentrators with single-axis external tracking
(Chapter, 2023)Microtracking concentrators enable the use of concentrator photovoltaics without the need for accurate two-axis external solar tracking. However, the wide tracking range required from stationary microtracking concentrators ... -
High-concentration wide-angle tracking integration with stacked lens arrays
(Chapter, 2019)Tracking-integration can reduce or eliminate the need for external solar tracking in CPV (concentrator photovoltaics). Previous research has shown how tracking-integrated systems can achieve high concentration ratios, wide ... -
High-performance polymer 3D printing – Open-source liquid cooled scalable printer design
(Peer reviewed; Journal article, 2022)To print high-performance polymers, a stable running printer that can reach high temperatures is needed. There is currently a lack of low-cost solutions that allow manipulation of process parameters and expansion of sensors ... -
High-performance stationary solar tracking through multi-objective optimization of beam-steering lens arrays
