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. ... -
Why we will all be looking for a new job soon, true story based on study case of Orkdal footbridge
(Chapter, 2017)The fourth industrial revolution, already present in the several industries, is now entering the field of civil engineering. Digital fabrication, mass customization, robot arms and drones are connected within the building ... -
Wind deflection analysis of railway catenary under crosswind based on nonlinear finite element model and wind tunnel test
(Peer reviewed; Journal article, 2022)This paper evaluates the railway catenary's wind deflection under crosswind based on wind tunnel experiments and a nonlinear finite element model. A catenary model is constructed based on the absolute nodal coordinate ... -
Wind Field Variability in Complex Terrain: Lessons from the Hardanger Bridge
(Chapter; Peer reviewed, 2019)Along the Coastal Highway E39 in the western coast of Norway, Norwegian Government is planning to build several extreme bridges spanning from 1.5 to 5 km. The region is typically mountainous with deep fjords seeping inland. ... -
Wind forces on bridge decks using state-of-the-art FSI methods
(Doctoral theses at NTNU;2019:180, Doctoral thesis, 2019)Several bridges with span widths that challenge present technology are currently under planning in Norway, and wind effects are among the major concerns. Traditionally, wind-structure interactions are studied experimentally ... -
Wind Induced Dynamic Response of Concrete Box Girders During a Balanced Cantilevered Construction Stage
