Finite Element Approximation of the Acoustic Impedance in Transducer Layers Comprising Silver Coated Monodisperse Polymer Spheres in a Polymer Adhesive
(Master thesis, 2017)In this work, we study the acoustic impedance of Isotropic Conductive Adhesives (ICAs) consisting of silver coated monodisperse polymer spheres. These ICAs are intended to be used as thermal conductive isolation and matching ... -
Finite Element Implementation of Fibre-Reinforced Materials Model in Abaqus/Explicit
(Master thesis, 2015)This thesis is concerned with the constitutive modelling of short fibre-reinforced composites in the finite element code Abaqus/Explicit. The model is presented as a generic framework which is based on a two-phase ... -
Finite element implementation of lower-order strain gradient plasticity in Abaqus
(Master thesis, 2015)A finite element method implementation of lower-order strain gradient plasticity is developed. Its validity is checked against known analytical solutions. The implementation gives expected trends when applied to particle ... -
Finite element modeling of porcine mitral valve apparatus using realistic annular motion from sono-crystal measurements and corresponding echocardiography
(Master thesis, 2020)En grundig og nøyaktig forståelse av mitralklaffens dynamikk er nødvendig og etterspurt for å utvikle gode prognoser for langtidsvirkningene av mitralklaffdefekter. Numeriske beregningsmetoder, deriblant elementmetoden ... -

Finite element modeling of porous polymer pipeline coating using X-ray micro computed tomography
(Journal article; Peer reviewed, 2019)Offshore pipelines are designed to sustain impact from fish trawl equipment and anchors, but due to component complexity, insulating coating solutions are often neglected in mechanical capacity estimates. In this work, ... -
Finite element modelling and experimental verification of timber halved and tabled scarf joints
(Peer reviewed; Journal article, 2022)Carpentry joints are very common in existing timber structures and they may gain attention for contemporary structures, due to their high degree of reversibility. Therefore, reliable Finite Element (FE) models for carpentry ... -
Finite element modelling of steel bridge structures exposed to ship collisions
(Master thesis, 2018)The behavior of the Bressan-Williams-Hill fracture criterion (BWH), which is often used in simulating ship collisions, was studied by modeling and studying existing experiments done on the subject. Three experiments are ... -
Finite element simulation of ductile fracture in polycrystalline materials using a regularized porous crystal plasticity model
(Peer reviewed; Journal article, 2021)In the present study, a hypoelastic–plastic formulation of porous crystal plasticity with a regularized version of Schmid’s law is proposed. The equation describing the effect of the voids on plasticity is modified to allow ... -
First principle calculations of pressure dependent yielding in solute strengthened aluminium alloys
(Journal article; Peer reviewed, 2020)The pressure dependence of the yield stress in solute strengthened aluminium alloys is investigated by first principle calculations. The solute elements studied are magnesium, silicon and copper. A fixed boundary cluster ... -
Fleksible nettkonstruksjoner som sikringstiltak mot sørpeskred i Vannledningsdalen
(Master thesis, 2021)I forprosjekteringen av ulike sikringsløsninger i Vannledningsdalen på Svalbard, er det kommet opp et forslag om bruk av fleksible nettkonstruksjoner som en del av et mulig tiltak mot sørpeskred. Det er ikke kjent at dette ... -
Floating wind turbines at medium water depths
(Master thesis, 2010)Offshore wind turbines have an enormous potential in terms of larger average wind speeds and low surface roughness compared to their onshore counterpart. Shallow water fixed wind turbines are ranked as a mature technology ... -
Flowable fibre-reinforced concrete for structural applications: A modelling approach that can take anisotropic and inhomogeneous fibre configuration into account
(Doctoral thesis at NTNU;2015:335, Doctoral thesis, 2015)The fibre orientation and distribution in a structural element cast with flowable fibrereinforced concrete (FRC) is affected by the concrete flow, which can enhance its nonuniform and anisotropic fibre configuration. The ... -
FlowCyl: one-parameter cement paste rheology test developed at NTNU, Norway
(Journal article, 2019)The FlowCyl is a simple flow viscometer – a modification of the Marsh Cone test apparatus developed to characterize cement pastes and grouts. The FlowCyl gives a one-parameter characterisation of rheology called the flow ... -
Fluid structure interaction aspects in obstructive sleep apnea patients
(Master thesis, 2017)In this master thesis, a comparative study of the feasibility of fluid-structure interaction (FSI) tools has been done in light of simulating the problem of obstructive-sleep apnea (OSA). Part of the study has been done ... -
Fluid Structure Interaction Simulation on an Idealized Aortic Arch
(Master thesis, 2012)The aortic arch is at risk of several cardiovascular diseases, such as aortic dissection. Many of these risk factors are due to the fluid-structure interaction that occurs in the aorta. Fluid-structure interation (FSI) ... -
Fluid-structure interaction effects during the dynamic response of clamped thin steel plates exposed to blast loading
(Peer reviewed; Journal article, 2021)This work presents results from a numerical investigation on the influence of fluid-structure interaction (FSI) on the dynamic response of thin steel plates subjected to blast loading. The loading was generated by a shock ... -
