Micromechanical Modelling of Strain Localization and Fracture in Aluminium
(Master thesis, 2012)Aluminium is often treated as a homogeneous material. However, when investigated on a microscopic scale, a granular structure is observed. The mechanical properties of the constituents, together with the distribution of ... -
Micromechanics-based identification of a ductile fracture model for three structural steels
(Journal article, 2020)From an engineering point of view, it is beneficial to reduce the number of mechanical tests required to calibrate the plasticity and fracture models of a structural material. In this study, the ductile fracture model for ... -
Microproportioning - Rheology of filler modified cement paste (matrix) with crushed aggregate fines and pozzolana
(Master thesis, 2018)This thesis presents a study on how crushed aggregate fines and pozzolana affects the rheological properties of a cement paste. Two approaches for investiagations of rheology properties were performed; mixing and measurements ... -
Microstructural changes and mass transport in cement-based materials: a modeling approach
(Peer reviewed; Journal article, 2021)A generic modeling framework is presented to relate microstructural changes, i.e. changes in the pore volume distribution and phase assemblage, and mass transport in cement-based materials. The modeling framework accounts ... -
Microstructure and mechanics of the bovine trachea: Layer specific investigations through SHG imaging and biaxial testing
(Peer reviewed; Journal article, 2022)The trachea is a complex tissue made up of hyaline cartilage, fibrous tissue, and muscle fibers. Currently, the knowledge of microscopic structural organization of these components and their role in determining the tissue’s ... -
Microstructure and nanomechanical behavior of an additively manufactured (CrCoNiFe)94Ti2Al4 high-entropy alloy
(Peer reviewed; Journal article, 2021)Recent substantial studies indicate that high-entropy alloys (HEAs) possess superior mechanical performance, including exceptional strength, high creep resistance, etc. However, additive manufacturing (AM), a burgeoning ... -
A microstructure informed and mixed-mode cohesive zone approach to simulating hydrogen embrittlement
(Peer reviewed; Journal article, 2022)Hydrogen induced failure under uniaxial tension is simulated in a duplex stainless steel considering microstructural feature of the material. There are three key ingredients in the modelling approach: image processing and ... -

Mikroproporsjoneringsmodellering med måling av maksimum partikkelpakning i fillermodifisert pasta og viskositet på pastavæske
(Master thesis, 2019)Det er tre hovedmetoder som ble undersøkt: måling av maksimum partikkelpakning ved sentrifugering, ekstraksjon av overflødig væske (EF) i fersk sementpasta og måling av viskositet av EF. Disse metodene ble utført i ... -
Mineralogical Sequence of Self-Healing Products in Cracked Marine Concrete
(Journal article; Peer reviewed, 2019)Self-healing of cracked concrete beams after 25 years of marine exposure was investigated. The extent of self-healing and the chemical and mineralogical composition of the self-healing products were characterized, and ... -
Mitral annular dynamics are influenced by left ventricular load and contractility in an acute animal model
(Peer reviewed; Journal article, 2023)The purpose of this study was to investigate the effects of loading conditions and left ventricular (LV) contractility on mitral annular dynamics. In 10 anesthetized pigs, eight piezoelectric transducers were implanted ... -
Modal Analysis and Damage Identification of the Hell Bridge Test Arena
(Master thesis, 2018)The purpose of the Hell Bridge test arena is to assess new sensor technology, monitoring algorithms and SHM techniques on a real structure in a controlled environment to establish reliable, cost-effective and time efficient ... -
Mode I stress intensity factors for semi-elliptical fatigue cracks in curved round bars
(Peer reviewed; Journal article, 2021)Some cyclically loaded components such as mooring chains can develop fatigue cracks in locations where the shape of the part is equivalent to that of a curved or bent round bar. Here we consider a semi-elliptical crack ... -
Model uncertainty assessment for wave- and current-induced global response of a curved floating pontoon bridge
(Peer reviewed; Journal article, 2020)The present paper provides a comparison between the numerical and experimental response for a generic floating pontoon bridge structure, thereby also serving to quantify the inherent uncertainties associated with both types ... -
