Foam Materials used for Energy Absorption and Damage Prevention during Blast Loading
(Master thesis, 2016)Following several high profile bomb attacks in the western hemisphere in recent years, e.g. Brussels 2016 and Norwegian government quarter 2011, the protection of structures against blast loading has received a lot of ... -
Focused ion beam milling of self-assembled magnetic superstructures: an approach to fabricate nanoporous materials with tunable porosity
(Journal article; Peer reviewed, 2018)Fabricating nanoporous materials with tunable pore sizes while keeping the freedom of materials choice, is an active area of research because of its practical relevance in a wide range of applications. Here, we demonstrate ... -
Foldede Formers Funksjonalitet - Konseptuell Design av Foldede Platekonstruksjoner i Betong
(Master thesis, 2017)Foldede platekonstruksjoner i betong kan visuelt sett beskrives som konstruksjoner sammensatt av en rekke plater med varierende helning, slik at det ser ut som konstruksjonen er foldet. For denne typen konstruksjoner er ... -
Foldedekker i betong
(Master thesis, 2011)Arkitekturen i Nye Deichmanske hovedbibliotek involverer store spenn kombinert med foldedekker i betong. Vestfasaden i bygget er planlagt med et utkraget foldedekke som spenner 21.5 m for å opprettholde siktlinjen til ... -
Forankring av rørgater i bratt terreng: Forsøk med materialer og metoder
(Master thesis, 2012)Denne oppgaven tar for seg forankring av nedgravde rørgater. Det er undersøkt interaksjonen mellom rør og jord, først i horisontalt terreng og deretter i bratt terreng med helning over 20 grader. I rapporten er det studert ... -
Forankring i betong - Neste generasjons Eurokode 2
(Master thesis, 2020)Det pågående arbeidet med å revidere Eurokode 2 del 1-1 nærmer seg slutten. Innarbeiding av nyere forskningsresultater, samt økt brukervennlighet, er stikkordene for revisjonen av hele Eurokode-serien. En av delene som ... -
Forankringskapasitet til murte forblendinger utsatt for jordskjelv
(Master thesis, 2013)Denne masteroppgaven omhandler praktiske forsøk utført for å dokumentere forankringskapasiteten til trådbindere fra horisontale mørtelfuger. Eksisterende konstruktive løsninger for forankring av skallmurvegger og forblendinger ... -
Force identification and response estimation in floating and suspension bridges using measured dynamic response
(Doctoral theses at NTNU;2019:88, Doctoral thesis, 2019)The trend of constructing bridges that are longer, more slender, and more flexible increases the importance of the assessment of dynamic behavior. Herein, it is imperative to have a good understanding of the environmental ... -
Form Closure For Fully Actuated and Robust Obstacle-Aided locomotion in Snake Robots
(Peer reviewed; Journal article, 2023)In this letter we adapt the theory of form closure to define the form closed region: The subset of a snake robot's configuration space for which the constraints imposed by the obstacles in its environment render the system ... -
Formability of aluminium alloy subjected to prestrain by rolling
(Doctoral thesis at NTNU;2014:363, Doctoral thesis, 2014)The purpose of this thesis was to improve the understanding and the accuracy of the description of metal sheet formability following the needs of the automotive industry. In particular, the effects of plastic anisotropy ... -
Formation of shlykovite and ASR-P1 in concrete under accelerated alkali-silica reaction at 60 and 80 °C
(Peer reviewed; Journal article, 2020)Three types of alkali-silica reaction (ASR) products, i.e., crystalline K-shlykovite, Na-shlykovite and nano-crystalline ASR-P1, have recently been synthesized at 80 °C. It is critical to verify the formation of these ASR ... -
Forming limit diagrams with an FE-based approach for sheets under non-proportional loading
(Chapter, 2009)In this study, LS-DYNA was used to predict the experimental forming limit diagrams (FLDs) for prestrained sheets in aluminum alloy Al2008-T4 found by Graf and Hosford [1]. The original data of Graf and Hosford [1] includes ... -
