Effects and Analysis of Crane Boom Impact Damage for Offshore Cranes
(Master thesis, 2018)Cranes are important constructions on offshore installations. Offshore cranes with latticed boom are exposed for unwanted collision with other objects, damaging the load-carrying structure. This thesis targets to detect ... -
Effects of a Passive Tuned Mass Damper on Blade Root Impacts During the Offshore Mating Process
(Peer reviewed; Journal article, 2020)Single-blade installation is a conventional method for installing blades on monopile-type offshore wind turbines. A jack-up crane vessel is commonly used, and individual blades are lifted to the tower top height and mated ... -
Effects of chloride, sulfate and pH on the corrosion of tensile wires in grouted tendon ducts in Herøysundet bridge
(Master thesis, 2022)Over lang tid har korrosjon av armering skapt problemer for betong strukturer og det er lagt ned mye forskning for å forstå hva som forårsaker det. Effektene av faktorer som pH-nivå, aggressive ioner, karbonatisering, stål ... -
Effects of different indentation methods on fatigue life extension of cracked specimens
(Journal article; Peer reviewed, 2018)In this paper, 3 different indentation methods have been investigated for crack arresting and fatigue life enhancement of cracked components. The influence of residual stresses induced by indentation on fatigue crack growth ... -
Effects of different production technologies on mechanical and metallurgical properties of precious metal denture alloys
(Journal article; Peer reviewed, 2017)Abstract: Background: Precious metal alloys can be supplied in traditional plate form orinnovative drop form with high degree of purity. Objective: The aim of the present work is to evaluate the influence of precious metal ... -
Effects of interlayer density and surfactant on coupled thermal stress and moisture absorption in modified montmorillonite/polypropylene nanocomposite
(Peer reviewed; Journal article, 2020)Modified montmorillonite/polypropylene nanocomposites (NCs) are increasingly used in industrial applications such as subsea pipelines because hexadecyltrimethyl ammonium montmorillonite (HDTMA+‐Mt) enhances thermomechanical ... -
The effects of learning environments on student active learning
(Chapter, 2023)Student active learning has been shown to have a significant positive effect on learning outcomes as experienced by students. The learning environments where these activities take place are often simplified to describe the ... -
Effects of load fluctuation on hydropower tunnels
(Doctoral thesis at NTNU;2015:280, Doctoral thesis, 2015)This dissertation presents a study of the main challenges and consequences of imposing rapid hydropeaking production patterns on unlined hydropower tunnels. It contains a thesis part and four research papers. The main ... -
The effects of microporosity in struts of gyroid lattice structures produced by laser powder bed fusion
(Peer reviewed; Journal article, 2020)Additive manufacturing by laser powder bed fusion allows the production of complex parts including lattice structures in popular metal alloys such as Ti6Al4V. Lattice structures are a class of meta-materials which hold ... -
The effects of the van der Waals potential energy on the Young’s modulus of a polymer: comparison between molecular dynamics simulation and experiment
(Journal article, 2021)Molecular dynamics simulation were employed to investigate the effect of changing the potential energies describing primary and secondary bonds on the Young’s modulus of a polymer. The energies were changed by arbitrarily ... -
Effects of Time Integration and Constraint Methods for Cable Simulations using ALE-ANCF Elements regarding Real-Time Analysis
(Doctoral theses at NTNU;2022:194, Doctoral thesis, 2022)The doctoral thesis by Gaute Fotland presents some of the requirements for developing a digital twin of an offshore crane. A digital twin will improve the control system for the crane with a real-time simulation. Furthermore, ... -
Effects of Urban Elements in Naturalistic Landscape: An Eye Tracking Study.
(Master thesis, 2023)Norge har en utrolig fin natur som det er verdt å ta vare på. Mange nordmenn liker hyttelivet og det bygges flere hytter hvert år. Disse hytten opptar plassen til naturen og utbyggingen stopper ikke. Det har blitt vist med ... -
Effects of Wind-Wave Misalignment on a Wind Turbine Blade Mating Process: Impact Velocities, Blade Root Damages and Structural Safety Assessment
(Peer reviewed; Journal article, 2020)Most wind turbine blades are assembled piece-by-piece onto the hub of a monopile-type offshore wind turbine using jack-up crane vessels. Despite the stable foundation of the lifting cranes, the mating process exhibits ... -
