Numerical modeling of diseased mitral valves
(Doctoral theses at NTNU;2023:273, Doctoral thesis, 2023)In this thesis, we have developed methods to create digital replicas of patients’ mitral valves from echocardiographic images and perform structural simulations in a finite element framework. The methods allow us to study ... -
Numerical modeling of liquefaction and its impact on anchor piles for floating offshore structures
(Journal article; Peer reviewed, 2019)Anchor piles and suction anchors have been used for anchoring different types of offshore structure in the past four decades. The recent growing interest and demand for wind energy has motivated the industry to evaluate ... -
Numerical modelling and analysis of the interactions between the left ventricle and the mitral valve
(Master thesis, 2018)In order to develop treatments for various heart diseases, a finite element model of the left ventricle and mitral valve apparatus could be of help. The goal of this thesis was to develop a finite element model of the left ... -
Numerical Modelling and Analysis of the Left Ventricle
(Master thesis, 2015)The development of a well functioning finite element model of the left ventricle is an important step to better understand the pumping function of the human heart. This may be of interest when developing effective treatments ... -
Numerical Modelling of Brittle Failure in Ice Structures
(Master thesis, 2014)The main purpose of this Master's thesis is to use finite element method to investigate if brittle failure in sea ice can be described in a force-displacement history. Four implemented material models in LS-Dyna are taken ... -
Numerical modelling of damping for timber structures in Abaqus
(Master thesis, 2020)Demping er en egenskap som påvirker den dynamiske responsen til trekonstruksjoner. Det er imidlertid en vanskelig oppgave å representere virkelig demping numerisk. I denne oppgaven er numerisk modellering av demping for ... -

Numerical modelling of field test for crack risk assessment of early age concrete containing fly ash
(Journal article; Peer reviewed, 2018)The high-strength/high-performance concretes are prone to cracking at early age due to low water/binder ratio. The replacement of cement with mineral additives such as fly ash and blast-furnace slag reduces the hydration ... -
Numerical Modelling of Laterally Loaded Piles in PLAXIS 3D - A study on embedded pile and soil response in PLAXIS 3D under lateral load
(Master thesis, 2016)Embedded pile element in PLAXIS 3D is an efficient method for pile foundation modelling. The current project provides an overall study on the embedded pile and surrounding soil response in PLAXIS 3D. The finite element ... -
Numerical modelling of moisture ingress in cracked concrete
(Master thesis, 2017)Concrete is a construction material which service life can be significantly reduced with the presence of cracks when concrete is exposed to aggressive agents such as chlorides. The current service life models for concrete ... -
Numerical modelling of the effects of crystallographic texture and grain structure on the macroscopic behaviour of metals
(Master thesis, 2010)The crystal plasticity theory derives the response of a crystalline material from its structure and the structural defects. This work tries to find this connection. The first part revises the main concepts of the plasticity ... -
Numerical modelling of Wood Microstructure
(Master thesis, 2015)The behaviour of wood is hard to predict due to the complex structure of the material. Wood consists of cells (fibres) arranged in an intricate pattern, and the behaviour of the material is a result of the behaviour of the ... -
Numerical Models for Dynamic Properties of a 14 Storey Timber Building
(Master thesis, 2012)The world tallest timber building with height of 45 meters, is planned for Bergen, Norway. In this master thesis the dynamic properties of the case building, as proposed by Sweco and Artec, are investigated. The proposed ... -
