An Experimental and Numerical Study of Thermoplastics at Large Deformations
(Doctoral thesis at NTNU;2016:191, Doctoral thesis, 2016)This thesis has examined the mechanical behavior of HDPE and PVC at large strains and at low to intermediate strain rates. This examination has been done by analyzing experimental results from uniaxial tension and ... -
Analysis of geometrical Nonlinearities – with Applications to Timber Structures
(Doctoral theses at NTNU;2005:74, Doctoral thesis, 2005)A large part of the study is concerned with geometrical nonlinearities in structural systems, primarily 3D frame type structures. Parametrizations of finite rotations are studied, and geometric terms associated with ... -
Application of marine field data for prediction of chloride ingress in concrete
(Doctoral theses at NTNU;2022:173, Doctoral thesis, 2022)A fixed link is about to be built across the Fehmarn Belt between Denmark and Germany. The main structure of the link is a submerged reinforced concrete tunnel with a design service life of 120 years considering corrosion ... -
Aspects of design of reinforced concrete structures using nonlinear finite element analyses
(Doctoral theses at NTNU;2017:149, Doctoral thesis, 2017)Non-linear finite element analyses (NLFEA) of reinforced concrete structures have gained much attention in the structural engineering community during the last decade, and the practising engineer is now equipped with an ... -
Atomic Insights into Hydrogen-Grain Boundary Interactions
(Doctoral theses at NTNU;2023:120, Doctoral thesis, 2023)Derived from the most abundant element in the universe, hydrogen is the smallest element and, at the same time, a clean, mobile, and efficient energy carrier. Nowadays, hydrogen is regarded as the fuel of future and could ... -
Atomistic Insight into Nanofluid Enabled Enhanced Oil Recovery
(Doctoral theses at NTNU;2023:72, Doctoral thesis, 2023)Nanoparticles (NPs) possess great potential in applications to enhanced oil recovery (EOR) due to their outstanding features of ultra-small size, great surface and interface effect, high sustainability, etc. The underlying ... -
Atomistic Insight into Transportation of Nanofluid in Ultra-confined Channel
(Doctoral theses at NTNU;2018:334, Doctoral thesis, 2018)Recently, a renewed interest arises in the application of nanofluids, nanoparticles (NPs) contained base fluid, for enhanced oil recovery (EOR) due to the potential of changing the fluid properties, wettability alternation ... -
