A Virtual Calibration Strategy and Its Validation for Large-Scale Models of Multi-Sheet Self-Piercing Rivet Connections
(Peer reviewed; Journal article, 2024) -
Virtuell virkelighet – bare en hype eller reell forbedring for konstruksjonsdesign?
(Master thesis, 2019)Formålet med denne avhandlingen er å undersøke om virtuell virkelighet (VR) bare er en teknologisk hype eller om den kan bidra til en reell forbedring for kontruksjonsdesign. Mange bedrifter bruker allerede VR som et ... -
Visco-elastic response of thermoplastics
(Master thesis, 2013)In this study a recently developed visco-elastic visco-plastic material model has been evaluated with the intention of improving the simulated behaviour of polymers. In order for polymers to become a more reliable construction ... -
Viscoelastic response of hydrogel materials at finite strains
(Master thesis, 2015)Hydrogel materials are very soft materials consisting of polymer networks and solvent molecules. The materials may exhibit large volume changes depending on its external chemical and mechanical environment and have ... -
Viscous regularization for cohesive zone modelling under constant displacement: an application to hydrogen embrittlement simulation
(Journal article; Peer reviewed, 2016)The convergence problem during the cohesive zone modelling of hydrogen embrittlement in constant displacement scenario is attributed to the numerical instability which is studied analytically in the present work. The ... -
Vitamin K2 modulates vitamin D induced mechanical properties of human 3D bone spheroids in vitro
(Peer reviewed; Journal article, 2020)Rotational culture promotes primary human osteoblasts (hOBs) to form three-dimensional (3D) multicellular spheroids with bone tissue-like structure without any scaffolding material. Cell-based bone models enable us to ... -
Void growth in calciumcarbonate filled PVC
(Master thesis, 2011)SIMLab has in recent years been developing a constitutive material model for polymer materials. Polymersoften experience volume change during plastic deformation, which is often related to damage in the material, such as ... -
Void nucleation and growth in mineral-filled PVC - An experimental and numerical study
(Journal article; Peer reviewed, 2014)The nucleation and growth of voids in mineral-filled PVC have been investigated through experimental and numerical studies. Uniaxial tensile specimens were deformed in tension to different elongation levels and then unloaded. ... -
Volume growth during uniaxial tension of particle-filled elastomers at various temperatures–Experiments and modelling
(Journal article; Peer reviewed, 2017)A common presumption for elastomeric material behaviour is incompressibility, however, the inclusion of filler particles might give rise to matrix-particle decohesion and subsequent volume growth. In this article, the ... -
Volumetric strain measurement of polymeric materials subjected to uniaxial tension
(Journal article; Peer reviewed, 2019)A novel method for measuring and calculating volumetric strain in circular cylindrical uniaxial tension samples made from polymeric materials is proposed. It is shown that special considerations must be taken when calculating ... -
Vurdering av basalt- og stålfibres effekt og mekaniske egenskaper i jetpeler
(Master thesis, 2012)Denne masteroppgaven er en eksperimentell studie av en selvkomprimerende konstruksjonsbetong (styrkeklasse B35) med antiutvaskingsegenskaper armert med enten basaltfiber (monofilament) eller stålfiber. Formålet med oppgaven ... -
Vurdering av formelverk for rissviddeberegning av armerte betongkonstruksjoner
(Master thesis, 2016)Dimensjonering i bruksgensetilstand innebærer å begrense nedbøyning, spenningsnivå og opprissing slik at betongkonstruksjonens bestandighet eller funksjon ikke svekkes. Denne avhandlingen fokuserer på kartlegging av ... -
Vurdering av stivhetskoeffisienter for søylesteg og overlappforbindelser
(Master thesis, 2018)Knutepunktstandarden (NS-EN 1993-1-8) angir regler og anbefalinger for dimensjonering og prosjektering av knutepunkter i stålkonstruksjoner. Ved globale analyser av konstruksjoner er det viktig å kunne anta innenfor rimelig ... -
V–H–M seismic capacity envelopes of strip foundations on slopes for capacity design of structure-foundation system
(Journal article; Peer reviewed, 2019)The columns and the supporting foundations are invariably subjected to the interacting axial force, V, shear force, H and moment, M. It is quite common to consider the interaction of these forces in design of structural ... -
Wedge splitting test of wood for fracture parameters estimation of Norway Spruce
(Peer reviewed; Journal article, 2020)Crack evolution in wood from Norway Spruce during mode I wedge splitting tests was measured using a Digital Image Correlation (DIC) system. The resulting series of deformation fields were post-processed in order to obtain ... -
Weinberg’s 3HDM potential with spontaneous CP violation
(Peer reviewed; Journal article, 2023)We study the potential of Weinberg’s Z2 × Z2-symmetric three-Higgs-doublet model. The potential is designed to accommodate CP violation in the scalar sector within a gauge theory, while at the same time allowing for natural ... -
Welding on Power Pylons in Aluminium
(Master thesis, 2016)This master thesis has investigated the behaviour of aluminium cylinders subjected to compression for both unwelded and welded cross sections. Three different combinations of material and geometry has been tested in the ... -
When and How Should Chloride Profiles be Calibrated for Paste Fraction?
(Peer reviewed; Journal article, 2022)Due to stochastic and systematic variations in the paste fraction, data for total chloride content are occasionally calibrated using parallelly measured calcium content as a measure of the actual paste fraction − assuming ... -
When Thermodynamic Properties of Adsorbed Films Depend on Size: Fundamental Theory and Case Study
(Peer reviewed; Journal article, 2020)Small system properties are known to depend on geometric variables in ways that are insignificant for macroscopic systems. Small system considerations are therefore usually added to the conventional description as needed. ...
