Validation and Analysis on Numerical Response of Super-High-Speed Railway Pantograph-Catenary Interaction Based on Experimental Test
(Peer reviewed; Journal article, 2021)The numerical tools can be used to facilitate the design of the railway pantograph-catenary system. The validation of the current numerical results is mostly performed at a speed slower than 350 km/h. This paper aims at ... -
Validation of material model for polypropylene (PP)
(Master thesis, 2012)A hyperelastic-viscoplastic material model intended for thermoplastics has been developed by SIMLab at NTNU. This model formed the basis of the thesis, where a material model for the polymer polypropylene was calibrated ... -
Validation of material model for polypropylene (PP)
(Master thesis, 2012)Polymers are the up and coming engineering material. The number of possibleapplications is increasing fast and so is the need for a good polymer material model. Thescientists at SIMLab at NTNU have developed such a material ... -
Validation study of failure prediction in crash analysis
(Chapter, 2008)Modeling of plastic deformation and failure is critical in crash analysis. In the present paper, we have studied one approach to represent instabilities and damage evolution in non-linear finite element analyses of forming ... -

(Master thesis, 2012)Denne rapporten tar for seg validering av en hyperelastisk viscoplastisk material modell som tidligere har blitt implementert i elementmetode koden LS Dyna. Materialet som er evaluert er polyetylen (HDPE) som er levert ... -
Validering av materialmodell for polyvinylklorid (PVC)
(Master thesis, 2012)En ny materialmodell for termoplaster ble utviklet ved SIMLab i 2010. Validering av denne er målet for denne oppgaven. Modellen implementeres i LS-DYNA som en brukerdefinert materialmodell og inneholder 11 parametre som ... -
Value of information of in-situ inspections of mooring lines
(Peer reviewed; Journal article, 2021)Mooring systems that are used to secure position keeping of floating offshore oil and gas facilities are subject to deterioration processes, such as pitting corrosion and fatigue crack growth. Past investigations show that ... -
Variant Creation of Onshore Steel Outfitting Structures
(Master thesis, 2010)Pipe racks are steel frame structures used to support piping, cables, trays etc. at oil and gas facilities onshore and offshore. Pipe racks may vary in design but thefundamental principals are the same. The geometry is ... -
Variation in predicting pantograph–catenary interaction contact forces, numerical simulations and field measurements
(Journal article; Peer reviewed, 2017)The contact force between the pantograph and the contact wire ensures energy transfer between the two. Too small of a force leads to arching and unstable energy transfer, while too large of a force leads to unnecessary ... -
A variational multiscale framework for atmospheric turbulent flows over complex environmental terrains
(Peer reviewed; Journal article, 2020)A residual-based variational multi-scale (VMS) modeling framework is applied to simulate atmospheric flow over complex environmental terrains. The VMS framework is verified and validated using two test cases using linear ... -

Velocity profiles in a 2D model of the left ventricular outflow tract, pathological case study using PIV and CFD modeling
(Chapter, 2017)In the current study, we present an experimental (in vitro) 2D flow model for studying blood flow in the human left ventricular outflow tract (LVOT) and the first part of the aorta using particle image velocimetry (PIV) ... -
VEqMon2D—Equations of motion generation tool of 2D vehicles with Matlab
(Journal article; Peer reviewed, 2022)The tool VEqMon2D provides a framework to generate analytical expressions of equations of motion of 2D vehicle models in Matlab. Such vehicle models are mostly used in studies that focus on the infrastructure (pavement, ... -
Verification of the dynamic properties of the Svinesund Bridge by wind-induced acceleration measurements
(Master thesis, 2012)The New Svinesund Bridge had its grand opening in June 2005. Due to the prerequisite that the new bridge should interplay with the old one, the final design ended up in a slender and aesthetic bridge. Because of the slender ... -
