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
(Peer reviewed; Journal article, 2020)This paper investigates large, plastic deflections of a square plate due to impact on calm water. Most research in the area has examined linear elastic structural responses to such impact, but hydrodynamic responses during ... -
Ice Abrasion and Bond Testing of Repair Mortars and High Performance Concrete
(Master thesis, 2013)The purpose of this thesis has been to investigate ice abrasion properties for three different repair mortars, and evaluate their behavior and properties in relation to a typical B60 offshore concrete and a B70 concrete. ... -
Ice abrasion of concrete, background theory and testing at the NTNU laboratory
(Master thesis, 2012)Ice abrasion has been reviewed. Concrete and ice and their most important properties in accordance to ice abrasion have been studied. Concrete strength and contact pressure between ice and concrete is found to be important ... -

ICE ABRASION ON MARINE CONCRETE STRUCTURES
(Doctoral thesis at NTNU;2015:189, Doctoral thesis, 2015)A significant amount of the world’s undiscovered oil- and gas resources are located North of the Arctic Circle. In the light of this, there is currently an increasing interest in developing necessary infrastructure to ... -
Ice abrasion testing of high performance concrete for offshore structures
(Chapter, 2019)Offshore concrete structures exposed to drifting sea ice have abrasion of the concrete surface caused by the mechanical contact between ice and concrete in the order of 0.1 to 1 mm per year. The concrete-ice abrasion ... -
Ice abrasion testing of HP concrete for offshore structures
(Chapter, 2019)Offshore structures can be exposed to drifting sea ice. The wear (abrasion) of the concrete surface caused by the mechanical contact between ice and concrete is in the order of 0.1–1 mm per year. The concrete-ice abrasion ... -
Identification of Material Properties of an Aluminium Alloy
(Master thesis, 2017)Uniaxial tension tests of small versus large round specimens and small versus large flat specimens from a 3XXX series aluminium alloy were carried out to identify the mechanical properties of the material. Different ... -
Identification of short-wavelength contact wire irregularities in electrified railway pantograph–catenary system
(Peer reviewed; Journal article, 2021)The effect of two common types of short-wavelength irregularities (local imperfections and periodic short-wavelength irregularities) of the railway catenary on the pantograph–catenary interaction performance are studied ... -
Identifikasjon av vindindusert dynamisk respons i Gjemnessundbrua
(Master thesis, 2014)Denne oppgaven tar for seg den vindinduserte dynamiske responsen i Gjemnessundbrua. Dette gjøres først gjennom systemidentifikasjon ved å finne aktuelle egenfrekvenser og egenmoder. Disse finnes ved å analysere tidsserier ... -
Identifying intermediate structures during water and hydrate phase transitions with machine learning
(Master thesis, 2023)Vannmolekyler er i stand til å komme i forskjellige former og kan danne forskjellige strukturer, som is. Vann har også evnen til å danne nye stoffer når det blander seg med andre forbindelser, som hydrater. Men hvordan ... -
IFC-based Element Mapping for Sustainable Construction: Optimising Reuse and Structural Integrity Assessment
(Master thesis, 2023)Bygg- og anleggsindustrien bidrar betydelig til globale klimagassutslipp og miljøforringelse gjennom sine nåværende praksiser. Den dominerende bruk-og-kast tilnærmingen til byggematerialer fører til et høyt energiforbruk ... -
