Time-variant reliability of dynamic systems by importance sampling and probabilistic analysis of ice loads
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:139, Doctoral thesis, 2006)The main objective of this thesis is to develop an efficient simulation technique to estimate the failure probability of time-dependent systems, whose state is expressed as a solution of Itô stochastic differential ... -
Topography studies of concrete abraded with ice
(Journal article; Peer reviewed, 2019)Topography studies of concrete-ice abrasion were made to proceed in our understanding of the mechanisms of concrete wear by ice on Arctic offshore structures. The effects on various initial surfaces of a B75 normal-weight ... -
Topology and polarity of dislocation cores dictate the strength of monolayer MoS2
(Journal article; Peer reviewed, 2019)In contrast to homoelemental graphene showing common dislocation dipole with pentagon-heptagon (5|7) core, heteroelemental MoS2 is observed to contain diverse dislocation cores that tune the chemical and physical properties. ... -
Toward identifying the ASR-induced stresses from displacement measurements and crack observations—Demonstration on a beam bridge in Norway
(Peer reviewed; Journal article, 2022)Alkali–silica reaction (ASR) in concrete causes expansion and degradation of the material, which might give adverse structural consequences. From the structural engineer point view, the greatest concern is if ASR leads to ... -
Towards a better understanding of the ultimate behaviour of lightweight aggregate concrete in compression and bending
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:123, Doctoral thesis, 2012)Ordinary normalweight concrete has a low strength-to-weight ratio compared to steel. This may prevent the use of concrete for the construction of tall buildings, floating structures, longspan bridges, etc. One way of ... -
Towards a better understanding of the ultimate behaviour of LWAC in compression and bending
(Journal article; Peer reviewed, 2017)There is a general scepticism regarding the use of lightweight aggregate concrete (LWAC) for structural applications. This concern is attached to the more brittle post-peak material behaviour and smoother crack surfaces ... -
Towards a generic physics-based machine learning model for geometry invariant thermal history prediction in additive manufacturing
(Peer reviewed; Journal article, 2022)Additive manufacturing (AM) is an emerging manufacturing technology that constructs complex parts through layer-by-layer deposition. The prediction and control of thermal fields during production of AM parts are of crucial ... -
Towards microstructure-informed material models for human brain tissue
(Peer reviewed; Journal article, 2020)Emerging evidence suggests that the mechanical behavior of the brain plays a critical role in development, disease, and aging. Recent studies have begun to characterize the mechanical behavior of gray and white matter ... -
Towards Novel Metal-Polymer Interface Thermal Transport Model Systems
(Master thesis, 2018)Enhanced control of thermal transport through metal-polymer interfaces is in demand as metal-polymer composites and organic electronics proliferate while continuous component miniaturization is pursued. Thermal conductivity ... -
Towards the Understanding of the pH Dependency of the Chloride Binding of Portland Cement Pastes
(Journal article; Peer reviewed, 2018)Hydrated Portland cement paste exposed to a NaCl solution was acidified by adding HCl in small steps, gradually lowering the pH. The chloride binding of the cement paste changed as a function of the pH. For the range of ... -
Towards the “sustainable” operation at -30 °C without the expense of energy for heating on-face electronics: intelligent heat conservation and waste heat utilization
(Journal article; Peer reviewed, 2022)On-face electronics (On-faceE) are urged to sense “anytime, anywhere” for enabling human senses to globally dominate the Internet of Things. However, with the limited lifetime of batteries and the miniaturization of the ... -
Traffic induced vibrations of cable-supported bridges
(Master thesis, 2016)When considering cable-supported bridges, forces from wind and earthquakes often governs design. Heavy vehicles can also excite considerable vibrations on long and slender bridges, and may excite other frequencies in the ... -
Train Classification Using a Weigh-in-Motion System and Associated Algorithms to Determine Fatigue Loads
(Peer reviewed; Journal article, 2022)This paper presents a methodology for classifying train passages into different types with a weigh-in-motion (WIM) system to allow the calibration of railway fatigue load models and identify individual vehicles from the ... -
Train-track-bridge modelling and review of parameters
(Journal article; Peer reviewed, 2016)This study gathers all necessary information to construct a model to calculate the coupled dynamic response of train–track–bridge systems. Each component of the model is presented in detail together with a review of possible ... -
Transferability of Temperature Evolution of Dissimilar Wire-Arc Additively Manufactured Components Using Finite Element Simulation through Machine Learning
(Peer reviewed; Journal article, 2024)Wire-arc additive manufacturing (WAAM) is a promising industrial production technique. Without optimization, inherent temperature gradients can cause powerful residual stresses and microstructural defects. There is therefore ... -
Transient pressure loading of clamped metallic plates with pre-formed holes
(Journal article; Peer reviewed, 2013)The combined effect of blast and impact loading against protective structures is still not fully understood. In this paper, the motivation is to investigate the combined effect of pressure and fragment loading on steel ... -
Transportation of Janus Nanoparticles in Confined Nanochannels: A Molecular Dynamics Simulations

Transverse Deformation of Pressurised Pipes With Different Axial Loads
(Chapter; Peer reviewed, 2017)Pipelines residing on the seabed are exposed to various hazards, one of them being denting, hooking and release of the pipeline by e.g. anchors or trawl gear. As a pipeline is displaced transversely in a hooking event, an ... -
Treatment of modelling uncertainty of NLFEA in fib Model Code 2020
(Peer reviewed; Journal article, 2021)When non-linear finite element analyses are used in design of new or assessment of existing concrete structures, one should account for the modelling uncertainty before conclusions are drawn based on the results. The present ... -
