An experimental and numerical study on the volume change of particle-filled elastomers in various loading modes
Ilseng, Arne; Skallerud, Bjørn Helge; Clausen, Arild Holm (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
Grimsmo, Erik Løhre; Clausen, Arild Holm; Langseth, Magnus; Aalberg, Arne (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 ... -
Analyse av boltede bjelke-søyle knutepunkt påkjent av bøyning om sterk og svak akse
Horvei, Herman Hagen (Master thesis, 2022)Anvendelse av elementmetoden for dimensjonering av stålkonstruksjoner har vokst frem som et raskere, enklere og mer nøyaktig alternativ enn å dimensjonere i henhold til Eurocode 3. IDEA StatiCa er et eksempel på programvare ... -
Analyse av et kaldformet kvadratisk hulprofil (undertittel: En sammenligning med og uten varmebehandling)
Stokke, Jon Sivert Hov (Master thesis, 2022)Kaldformede hulprofiler er attraktivt for mange ulike konstruksjonsdeler på grunn av sin høye styrke og relativt lave pris. På grunn av produksjonsmetoden inneholder slike profiler ofte store egenspenninger. det er viktig ... -
Anisotropic tensile behaviour of short glass-fibre reinforced polyamide-6
Holmström, Petter Henrik; Hopperstad, Odd Sture; Clausen, Arild Holm (Peer reviewed; Journal article, 2020)This paper presents an experimental investigation of injection-moulded short glass-fibre reinforced polyamide-6 reinforced with 0 wt.%, 15 wt.% and 30 wt.% fibres. The fibre orientation distributions are characterized by ... -
Beam - Column Connections Subjected to Static and Dynamic Loading
Frich, Herman (Master thesis, 2014)Bolted beam-column connections are commonly used in office buildings and off-shore platforms in Norway. The use of pre-fabricated components in frame structures is popular due to the cost effective and quick erection of ... -
