An isogeometric finite element-boundary element approach for the vibration analysis of submerged thin-walled structures
(Peer reviewed; Journal article, 2021)In this paper, the isogeometric formulations of the finite element and boundary element methods are applied to the dynamic analysis of thin-walled structures submerged in an infinite, inviscid, and incompressible fluid ... -
Isogeometric Kirchhoff-Love shell formulation for elasto-plasticity
(Journal article; Peer reviewed, 2018)An isogeometric thin shell formulation allowing for large-strain plastic deformation is presented. A stress-based approach is adopted, which means that the constitutive equations are evaluated at different integration ... -
Isogeometric methods for CFD and FSI-simulation of flow around turbine blades
(Journal article; Peer reviewed, 2015)Coupled fluid-structure interaction simulations of wind turbines have traditionally been considered computationally too expensive to carry out. However, more powerful computers and better solution techniques based on ... -
Isogeometric Modeling and Experimental Investigation of Moving-Domain Bridge Aerodynamics
(Journal article; Peer reviewed, 2019)Computational fluid dynamics (CFD) and fluid–structure interaction (FSI) are growing disciplines in the aeroelastic analysis and design of long-span bridges, which, with their bluff body characteristics, offer major ... -
Isogeometric Phase-Field Methods for Modeling Fracture in Shell Structures
(Doctoral theses at NTNU;2021:87, Doctoral thesis, 2021)The simulation of the fracture of engineering structures is a challenging topic that requires accurate and efficient numerical models. This thesis focuses on the modeling of brittle and ductile fracture in thin shell structures ... -
Isogeometric Structural Analysis of Wind Turbine Blades
(Master thesis, 2018)Isogeometric analysis, IGA, seeks to bridge the gap between engineering design and computational analysis by using spline functions as finite element bases in the analysis framework. The general concept can be applied to ... -
Isolasjon; Trefiber vs mineralull Sammenlikning og vurdering av måleresultater fra test-hus på Huntonstranda samt livsløpsvurderinger
(Bachelor thesis, 2021)Oppgaven undersøker om trefiberisolasjonens hygrotermiske egenskaper vil påvirke varmegjennomgangen og redusere energibehov i bygg. Dette er gjort gjennom litteraturstudie og analyse av måleresultater fra testhus etablert ... -
ISRM Suggested Method for Determining the Basic Friction Angle of Planar Rock Surfaces by Means of Tilt Tests
(Peer reviewed; Journal article, 2018)The basic friction angle plays a key role when estimating the shear strength of discontinuities for rock engineering projects, since a large body of research has shown that rock joint shear strength models that consider ... -
The ISSC 2022 committee III.1-Ultimate strength benchmark study on the ultimate limit state analysis of a stiffened plate structure subjected to uniaxial compressive loads
(Peer reviewed; Journal article, 2021)This paper presents a benchmark study on the ultimate limit state analysis of a stiffened plate structure subjected to uniaxial compressive loads, initiated and coordinated by the ISSC 2022 technical committee III.1-Ultimate ... -
ISUM for Offshore Frame Structures
(Chapter; Peer reviewed, 2016)The paper presents the background and major ideas behind the computer program USFOS. The program is today widely used by the offshore industry to assess the resistance of oil and gas installations against abnormal environmental ... -
Iterasjonsmetoden for kapasitetsberegning av armert betong
(Master thesis, 2013)Iterasjonsmetoden brukes til å kontrollere kapasiteten til armert betongmed kjent betongklasse, geometri, armeringsmengde og ytre last. Med utgangspunkt i ytre lastvektor finner man tøyninger i armering og betong somgir ... -
Iterative Development of Biomedical Equipment Based on Ultrasonic Frequency
(Master thesis, 2019)I samarbeid med St. Olavs og Biobank 1 har prosjektet til formål å prototype, iterere og teste et kuttekonsept og verktøy for kutting av prostataprøver som forberedelse til videre analyse (genuttrykksanalyse og MR-spektroskopi ... -
Iteratively coupled implicit dynamic MPM-FVM
(Doctoral theses at NTNU;2019:19, Doctoral thesis, 2019)Several geotechnical engineering problems involve the interaction between deformation of the soil skeleton and the development of pore water pressures. Very often the deformations are considered to be small, which opens ... -
ITS SOLUTIONS FOR DETECTION OF REDUCED MOBILITY
(Master thesis, 2019)I denne masteroppgaven har hastighetsprofilanalyse blitt fremmet som en potensiell parameter for gjenkjenning av redusert mobilitet blant tunge kjøretøyer i stigning. Tre nye ITS-teknologier ble testet for deteksjon av ... -
Ivar Aasen Field Development: How Inflow Control Devices Affect Oil Recovery and Project Economics
(Master thesis, 2014)Simulations for screen-only, ICD and AICD completions in the Ivar Aasen wells have been performed by Schlumberger on behalf of Det norske oljeselskap ASA. A screen-only completion has been used as a base case, to evaluate ... -
Jakten på kontrastene. En litteraturstudie om visuelle kontraster.
