Numerical analysis of hemodynamics in the left part of the heart, including simplified fluid-structure interaction methods
(Master thesis, 2010)The mitral valve is placed between the left atrium and ventricle. Both intra ventricular blood flow as well as valve dynamics are often subject to research. However, the inlet properties for such flows, which are created ... -
Numerical Analysis of Primary Stability on Cementless Hip Prostheses
(Master thesis, 2012)Since the first Total Hip Arthroplasty (THA) performed in the 60's, it has been regarded among the most successful surgical procedures. When an un-cemented hip prosthesis is employed, the prosthesis is impacted into a ... -
Numerical Analysis of the Dynamic Behaviour of Railway Catenary Systems in Accordance with Norwegian Conditions
(Master thesis, 2013)The dynamic behaviour of the railway catenary system is of great importance as the speed of the train increases. The aim for this study was to make a numerical model of the catenary system in three dimensions to be able ... -
Numerical Analysis of the Dynamic Response of Existing Railway Bridges.
(Master thesis, 2014)The railway is an important part of the infrastructure in todays society and there is a need to increase the capacity and verify the existing railway network to face the challenges of tomorrow. To meet todays and the future ... -
Numerical analysis of the impact of cytoskeletal actin filament density alterations onto the diffusive vesicle-mediated cell transport
(Peer reviewed; Journal article, 2021)The interior of a eukaryotic cell is a highly complex composite material which consists of water, structural scaffoldings, organelles, and various biomolecular solutes. All these components serve as obstacles that impede ... -
Numerical Analysis of Threaded Rods
(Master thesis, 2023)Denne masteroppgaven er en numerisk analyse av gjengede stag innskrudd i treverk. To modeller ble forsøkt kalibrert basert på eksperimentelle resultater. En modell hadde et gjenget stag utsatt for aksialkraft, i både trykk ... -
Numerical and experimental studies for damage detection and structural health monitoring of steel bridges
(Doctoral theses at NTNU;2021:382, Doctoral thesis, 2021)There is a vast number of existing bridges in infrastructure that are approaching or have exceeded their original design lives. A large part of these bridges are steel and composite steel-concrete bridges. The primary ... -
Numerical and physical modelling of oil spreading in broken ice
(Dr. ingeniøravhandling, 0809-103X; 2002:130, Doctoral thesis, 2003)The present work focus on oil spreading in broken ice, and the content of this thesis falls into three categories: • The physical and numerical modelling of oil spreading in ice. • Ice models, and parameters describing ... -
Numerical aspects of anisotropic failure in soft biological tissues favor energy-based criteria: A rate-dependent anisotropic crack phase-field model
(Journal article; Peer reviewed, 2018)A deeper understanding to predict fracture in soft biological tissues is of crucial importance to better guide and improve medical monitoring, planning of surgical interventions and risk assessment of diseases such as ... -
Numerical Evaluation of Modal Properties Change of Railway Bridges during Train Passage
(Journal article; Peer reviewed, 2017)During the passage of vehicles over a bridge, both systems (vehicle and bridge) are coupled together. This coupling is generally accounted for in vehicle-bridge interaction analyses. It is also commonly acknowledged that ... -
Numerical implementation of a non-local GTN model for explicit FE simulation of ductile damage and fracture
(Journal article, 2021)In this study, we follow the work of Tvergaard and Needleman (1995, 1997) and Needleman and Tvergaard (1998) and present the numerical implementation and initial applications of a non-local Gurson-Tvergaard-Needleman (GTN) ... -
Numerical Implementation of Brittle Failure Model for Glass
(Master thesis, 2017)This thesis is concerned with a strength model for float glass. Failure of glass is usually initiated from surface flaws and the glass is reckoned as failed with the first failing flaw. The model implements a flaw map over ... -
Numerical investigation into the effects of corrosion on the shear performance of pretensioned bridge girders with cast-in-place slabs
(Peer reviewed; Journal article, 2022)Corrosion and shear cracking are frequently observed near supports of pretensioned bridge girders in coastal climates, so non-linear finite element analysis was used to study the effect of corrosion on shear performance ... -
Numerical Investigation of 3D Scanned Mooring Chains - Effects of Stress Concentrations from Corrosion Pits
(Master thesis, 2017)This thesis aims to numerically evaluate severe corrosion pits on offshore mooring chain. Pitting corrosion is considered a significant degradation mechanism as cracks tend to nucleate and propagate in areas of high stress ... -
Numerical investigation of a novel pattern for reducing residual stress in additive manufacturing
(Journal article; Peer reviewed, 2020)Deposition patterns can significantly affect residual stress distribution in additive manufacturing processes. In this paper, a novel deposition pattern, the S-pattern, is proposed for the additive manufacturing process. ... -
