Alkali Aggregate Reactions (AAR) in Norway: Thin section analysis and expansion measurements from a dam and a bridge
(Peer reviewed; Journal article, 1992)Two concrete structures with AAR have been investigated. The structures are a dam and a bridge, both approximately 30 years old. Both structures have a characteristic crack pattern on the surface of the concrete. Thin ... -
Alkali metal distribution in composite cement pastes and its relation to accelerated ASR tests
(Peer reviewed; Journal article, 2023)Accelerated testing of alkali silica reaction (ASR) in concrete at elevated temperatures of 38 and 60 °C has an unknown impact on the alkali metal distribution in the cement paste. This paper investigates how the alkali ... -
Alkali-silica reaction (ASR)-performance testing: Influence of specimen pre-treatment, exposure conditions and prism size on alkali leaching and prism expansion
(Journal article; Peer reviewed, 2013)Whether or not concrete prism tests developed for assessment of alkali–silica reactivity of aggregates might be suitable for general ASR performance testing of concrete has been evaluated. This paper discusses how variations ... -
Alkali–silica reaction (ASR)—performance testing: Influence of specimen pre-treatment, exposure conditions and prism size on concrete porosity, moisture state and transport properties
(Journal article; Peer reviewed, 2013)Whether or not concrete prism tests (CPTs) developed for assessment of alkali–silica reactivity of aggregates might be suitable for general ASR performance testing of concrete has been evaluated. This paper presents the ... -
Aluminium plates with geometrical defects subjected to low-velocity impact: Experiments and simulations
(Peer reviewed; Journal article, 2022)In this paper, an experimental and numerical program investigating impact in the low-velocity regime ( m/s) on 1.5 mm thick AA6016 aluminium plates in three different heat treatments (T4/T6/T7) is presented. The tests were ... -
Aluminium Self-Piercing Rivet's Failure: Testing and Numerical Analyses
(Journal article; Peer reviewed, 2014)In the present study, the behaviour of aluminium rivets in alloy AA7278-T6 during the riveting process when used to join two aluminium plates was investigated experimentally and numerically. It was observed by Hoang et al. ... -
Aluminum foam-filled extrusions subjected to oblique loading: experimental and numerical study
(Journal article; Peer reviewed, 2004)The behavior of empty and foam-filled square thin-walled aluminum columns in alloy AA6060 subjected to quasi-static oblique loading was examined. Previous studies have shown that by introducing a load angle, the energy ... -
An enhanced forced vibration rig for wind tunnel testing of bridge deck section models in arbitrary motion
(Journal article, 2017)This paper presents a new experimental setup for the aerodynamic section model testing of bridge decks. The rig is designed to move a section model in arbitrary motion in a wind tunnel to imitate the motions of such scaled ... -
An enhanced identification procedure to determine the rational functions and aerodynamic derivatives of bridge decks
(Journal article, 2018)Development of time-efficient and reliable methods for estimating the aeroelastic properties of bridge decks is of major importance for bridge engineers to make wind tunnel testing more productive and less expensive. This ... -
An experimental and numerical study on the volume change of particle-filled elastomers in various loading modes
(Journal article; Peer reviewed, 2017)Laboratory tests show that there is a pronounced difference in the volumetric response between uniaxial tension and confined axial compression loading for commercial particle-filled hydrogenated nitrile butadiene rubber ... -
An experimental study of static and dynamic behaviour of bolted end-plate joints of steel
(Journal article; Peer reviewed, 2015)Many actions, such as accidental or malicious explosions, may impose high loading rates to structural frames. To enhance the knowledge of the behaviour of joints subjected to severe impulsive loading, a double-sided ... -
An experimental study on the deformation and fracture modes of steel projectiles during impact
(Journal article, 2013)Previous investigations of the penetration and perforation of high-strength steel plates struck by hardened steel projectiles have shown that under certain test conditions the projectile may fracture or even fragment upon ... -
An experimental-numerical method to determine the work-hardening of anisotropic ductile materials at large strains
(Journal article; Peer reviewed, 2014)The determination of work-hardening for ductile materials at large strains is difficult to perform in the framework of usual tensile tests because of the geometrical instability and necking in the specimen at relatively ... -
An explicit integration scheme for hypo-elastic viscoplastic crystal plasticity
(Journal article; Peer reviewed, 2014)An explicit integration scheme for rate-dependent crystal plasticity (CP) has been developed in this work. Additive decomposition of the velocity gradient tensor into lattice and plastic parts is adopted for describing the ... -
An exponential constitutive model excluding fibres under compression: Application to extension–inflation of a residually stressed carotid artery
(Journal article; Peer reviewed, 2018)Detailed information on the three-dimensional dispersion of collagen fibres within layers of healthy and diseased soft biological tissues has been reported recently. Previously we have proposed a constitutive model for ... -
Analysing limitations of the FlowCyl as a one-point viscometer test for cement paste
