HTR: An ultra-high speed algorithm for cage recognition of clathrate hydrates
(Peer reviewed; Journal article, 2022)Clathrate hydrates find diverse significant applications including but not limited to future energy resources, gas storage and transport, gas separation, water desalination, and refrigeration. Studies on the nucleation, ... -
Hullkantfasthet og stivhet av gjengestenger i bartrevirke.
(Master thesis, 2020)En av de viktigste komponentene for en konstruktør er den mekaniske egenskapen for et knutepunkt eller forbindelse. Manglende kunnskap om hullkantfasthet i trekonstruksjon ved bruk av gjengestenger eller annen type stav, ... -

Hvordan ta hensyn til ubalanserte momenter i beregning av gjennomlokking for flatdekkekonstruksjoner.
(Master thesis, 2020)Når et betongdekke ikke lenger har nok skjærkapasitet til å ta opp skjærkrefter tilført fra den konsentrerte punktlasten i søylen, vil det oppstå gjennomlokking. Tidligere ble utvidet oppleggsflaten på søyletoppen ofte ... -
Hybrid Concrete Structures: Experimental Testing and Numerical Simulation of Structural Elements
(Master thesis, 2010)The Composite Sandwich Slab (CSS) studied in this report is a hybrid concrete structure with different concrete types in zones of high versus low stresses. The CSS is a combination of a precast concrete formwork and in-situ ... -
Hybride betongkonstruksjoner
(Master thesis, 2010)Denne oppgaven tar for seg beregning og testing av hybride betongkonstruksjoner. Den inneholder også beskrivelse av materialtester. Bjelkene som testes er tenkt å være utsnitt av dekkekonstruksjoner. Konstruksjonene skal ... -

Hydrodynamic analysis and structural design of the Concrete Star Wind Floater
(Master thesis, 2013)This thesis was initiated by Trond Landbø from Dr.techn. Olav Olsen after an internship there during the summer of 2012. Amongst other projects, Dr.techn. Olav Olsen works with different concepts for floating concrete hulls ... -
Hydrodynamic interaction of floating bridge pontoons and its effect on the bridge dynamic responses
(Peer reviewed; Journal article, 2022)As pontoons of floating bridges respond to the dynamic actions of the wind and wave loading, additional forces are imposed on the pontoons due to the hydrodynamic interaction of these floating bodies. The wave forces on a ... -

Hydrogen embrittlement in steels: predictive models and integrity assessment
(Doctoral theses at NTNU;2023:123, Doctoral thesis, 2023)Hydrogen embrittlement (HE) is a well-recognized challenge as it can degrade the mechanical properties of most structural steels, leading to premature failure of hydrogen infrastructures. Continuum scale simulation is an ... -
Hydrogen informed Gurson model for hydrogen embrittlement simulation
(Journal article; Peer reviewed, 2019)Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the ... -
Hydrogen stress cracking and crack initiation in precipitation hardened Ni-alloys
(Journal article; Peer reviewed, 2018)The two different precipitation hardened nickel alloys, Alloy 718 and Alloy 725, were tested in its as received condition. Their susceptibility to hydrogen stress cracking was examined by the use of stepwise increasing ... -
Hydrogen trapping and diffusion in polycrystalline nickel: the spectrum of grain boundary segregation
(Peer reviewed; Journal article, 2024)Hydrogen as an interstitial solute at grain boundaries (GBs) can have a catastrophic impact on the mechanical properties of many metals. Despite the global research effort, the underlying hydrogen-GB interactions in ... -

Hydrogen-enhanced grain boundary vacancy stockpiling causes transgranular to intergranular fracture transition
(Journal article; Peer reviewed, 2022)The attention to hydrogen embrittlement (HE) has been intensified recently in the light of hydrogen as a carbon-free energy carrier. Despite worldwide research, the multifaceted HE mechanism remains a matter of debate. ... -
Hydrogen-induced cracking and hydrogen embrittlement of Ni2MnGa FSMAs
(Journal article; Peer reviewed, 2010)Hydrogen-induced cracking and hydrogen embrittlement of Ni50Mn30Ga20 ferromagnetic shape memory alloys (FSMAs) were studied through indentation and tension experiments supplemented with in situ observation. The results ... -
Hydrogen-induced transgranular to intergranular fracture transition in bi-crystalline Nickel
(Peer reviewed; Journal article, 2021)It is known that hydrogen can influence the dislocation plasticity and fracture mode transition of metallic materials, however, the nanoscale interaction mechanism between hydrogen and grain boundary largely remains illusive. ... -
Hydrogen-microvoid interactions at continuum scale
(Journal article; Peer reviewed, 2018)Experimentally, it has been shown that hydrogen can either enhance the internal necking failure or induce internal shearing failure of microvoids. In this study, the numerical investigation of hydrogen-microvoid interactions ... -
Hydroplastic response of a square plate due to impact on calm water
