On the use of a virtual laboratory for aluminium alloys: application to large-scale analyses of extruded profiles
(Doctoral theses at NTNU;2022:199, Doctoral thesis, 2022)The global effort of decreasing energy consumption and CO2 emissions has resulted in an important increase in the use of aluminium in the automotive sector. Aluminium (in the form of aluminium alloys) possesses many ... -
Modeling and experiments in transient potential drop measurements for non-destructive evaluation
(Doctoral theses at NTNU;2022:146, Doctoral thesis, 2022)Electromagnetic non-destructive evaluation methods are commonly used in inspection and health monitoring of steel structures. The electromagnetic properties of ferromagnetic steel are well known for being correlated with ... -
Ductile fracture of aluminium alloys in the low to moderate stress triaxiality range
(Doctoral theses at NTNU;2022:150, Doctoral thesis, 2022)This thesis investigates the effect of constituent particles on ductile fracture in 6000-series aluminium alloys in the low to moderate stress triaxiality range. In Part 1, tension tests on smooth and notched specimens ... -
Application of marine field data for prediction of chloride ingress in concrete
(Doctoral theses at NTNU;2022:173, Doctoral thesis, 2022)A fixed link is about to be built across the Fehmarn Belt between Denmark and Germany. The main structure of the link is a submerged reinforced concrete tunnel with a design service life of 120 years considering corrosion ... -
Atomistic insights into the droplet size evolution during self-microemulsification
(Peer reviewed; Journal article, 2022)Microemulsions have been attracting great attention for their importance in various fields including nanomaterials fabrication, food industry, drug delivery, and enhanced oil recovery. Atomistic insights into the ... -
Treatment of modelling uncertainty of NLFEA in fib Model Code 2020
(Peer reviewed; Journal article, 2021)When non-linear finite element analyses are used in design of new or assessment of existing concrete structures, one should account for the modelling uncertainty before conclusions are drawn based on the results. The present ... -
Probabilistic modelling of wind induced load effects for suspension bridges with emphasis on long-term extreme value analysis
(Doctoral theses at NTNU;2022:218, Doctoral thesis, 2022)Economic development has gradually promoted an increase in the demand for and size of long-span bridges worldwide. A tangible example of such development is the Coastal Highway Route E39 led by the Norwegian Public Roads ... -
An experimental investigation of the mechanical properties of axially loaded threaded rods embedded in glued-laminated timber elements
(Master thesis, 2022)Abstract will be available on 2025-06-11 -
Behavior of Post-Tensioned concrete box girder with multiple damaged tendons A Case Study of the Sykkylvsbrua
(Master thesis, 2022)Hovedformålet med denne masteroppgaven var å undersøke skadene i enkelt støttede boksbjelkerbroer. Dette ble utført ved å utføre ikke-lineær analyse i Finite elementanalyseprogrammet DIANA FEA 10.5 Oppgaven er delt inn i ... -
One the use of Machine Learning in the design of structures.
(Master thesis, 2022)FE-analyse kan tilnærmes på en maskin-lærings måte. Man kan tolke simuleringene som input til nevrale netverks modeller og forsøke å predikere en eller flere output. Denne masteroppgaven utforsker hvor godt modellene ... -
A siamese network-based non-contact measurement method for railway catenary uplift trained in a free vibration test
(Peer reviewed; Journal article, 2020)The vibration of the catenary that is initiated by the passing pantograph has a direct influence on the pantograph–catenary contact performance. Monitoring the dynamic uplift of the catenary can help inspectors to evaluate ... -
Constitutive modeling of a graded porous polymer based on X-ray computed tomography
(Peer reviewed; Journal article, 2020)This work focuses on the constitutive modeling of a graded porous polymer pipeline coating based on X-ray micro computed tomography (XRMCT). Previous work has revealed that finite element (FE) models generated from XRMCT ... -
Use of Concrete for Road Infrastructure: A SWOT Analysis Related to the three Catchwords Sustainability, Industrialisation and Digitalisation.
(Peer reviewed; Journal article, 2019)This paper aims at identifying the direction for more sustainable development of the use of concrete in road infrastructure in an industrialised context. The increase in the global mean temperature is one of the most severe ... -
The effect of infill walls on the seismic behavior of boundary columns in RC frames
(Peer reviewed; Journal article, 2016)scaled, three-story three-bay RC frame with masonry infill walls was studied experimentally and numerically. Pseudo-dynamic test results showed that despite following the column design provisions of modern seismic codes ... -
Steel beams with unstiffened web openings
(Master thesis, 2022)Den europeiske standardiseringskomiteen, CEN, har jobbet med en utvidelse av Eurokode 3: Design av stålkonstruksjoner – Del 1-1: Generelle regler og regler for bygninger, som skal hete «EN 1993-1-13: Bjelker med åpninger ... -
Onion inspired hydrate-phobic surfaces
(Peer reviewed; Journal article, 2022)Hydrate plugging in gas- and oil-production and transport systems has long been a critical challenge. Traditional hydrate mitigation strategies through applying chemicals and thermal destabilization are costly and ... -
Ballistic impact of structural steels at low temperatures
(Peer reviewed; Journal article, 2022)Steels are usually stronger at low temperatures than at high temperatures. But low temperatures are, particularly in combination with high strain rates and high stress triaxiality ratios, known to cause embrittlement. The ...
