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 ... -
