Fatigue reliability of offshore Mooring chains under influence of mean load and corrosion
(Doctoral theses at NTNU;2023:196, Doctoral thesis, 2023)A number of full-scale fatigue tests have been conducted for offshore mooring chain in the last decade for both new and used chains, retrieved after operation in the North Sea. The surface condition of the used chains vary ... -
Fatigue Reliability-Based Inspection and Maintenance Planning of Gearbox Components in Wind Turbine Drivetrains
(Journal article; Peer reviewed, 2014)This paper introduces a reliability-based maintenance plan for wind turbine gearbox components. The gears and bearings are graded based on their fatigue damage and a maintenance map is developed to focus on those components ... -
Fatigue Resistance of Double Sealant Composed of Polyisobutylene Sealant Adjacent to Silicone Sealant
(Journal article; Peer reviewed, 2014)With the aid of current sealant technologies, a double sealant comprising adjacent silicone and polyisobutylene sealants may be used to enhance the durability of buildings. The inner silicone sealant is quite durable owing ... -
Fatigue sensitivity to foundation modelling in different operational states for the DTU 10MW monopile-based offshore wind turbine
(Journal article; Peer reviewed, 2019)The importance of foundation modelling for the support-structure fatigue damage estimation of a 10 MW monopile based offshore wind turbine is investigated in different operational states and wind-wave misalignment conditions. ... -

Fatigue strength assessment of riveted railway bridge details based on regression analyses combined with probabilistic models
(Peer reviewed; Journal article, 2023)With the increasing attention on structural reliability and integrity, the probabilistic fatigue behaviour of riveted joints is drawn more attention, more specifically in the influence that this may have on the fatigue ... -
Fatigue Strength Assessment of Steel Rollers: On the Reliability of the Strain Energy Density Approach on Real Components
(Journal article; Peer reviewed, 2018)Welded joints are one of the most widely applied methods to join different steel components. However, they introduce stress concentrators that are commonly known to reduce the fatigue strength of structures. Several methods ... -
Fatigue strength of blunt V-notched specimens produced by selective laser melting of Ti-6Al-4V
(Journal article, 2018)Selective Laser Melting (SLM) process is an Additive Manufacturing (AM) technique that allows producing metallic parts of any kind of geometry with densities greater than 99.5%. Complex shapes lead however to notches with ... -
Fatigue Strength of Glued-Laminated Timber Loaded in Shear Along Grain and Withdrawal of Threaded Rods.
(Master thesis, 2017)This thesis involves the investigation of both static and fatigue performance of two different longitudinal shear situations. The first being axially loaded threaded rods with small rod to grain angles. The second situation ... -
Fatigue Strength of Titanium Risers - Defect Sensitivity
(Dr.ingeniøravhandling, 0809-103X; 2001:73, Doctoral thesis, 2001)This study is centered on assessment of the fatigue strength of titanium fusion welds for deep-water riser’s applications. Deep-water risers are subjected to significant fatigue loading. Relevant fatigue data for titanium ... -
Fatigue Study of Copper Conductors
(Master thesis, 2014)This master thesis was carried out during the spring semester of 2014 at Department of Marine Technology in Norwegian University of Science and Technology. It was a continuous work of the master project during autumn ... -
Fatigue, Cortisol and ACT: A pre-post study on the effects of workrelated rehabilitation
(Master thesis, 2013)Objective: There is evidence that chronic stess leads to sustained levels of arousal, causing a dysregulation of the stress response. Patients with chronic fatigue often suffer from hypocortisolim. This study aimed to find ... -
Fatigue, fysisk aktivitet og sykepleie.
(Bachelor thesis, 2021)Bakgrunn Fatigue kan beskrives som et fenomen, og følges av symptomer som blant annet utmattelse og kraftløshet. Omtrent 11 prosent av den norske befolkningen er rammet av tilstanden i ulik grad, og utbredelsen er økende ... -
Fatigue-related gait adaptations in children with cerebral palsy
(Peer reviewed; Journal article, 2023)Aim To obtain insights into the effects of fatigue on the kinematics, kinetics, and energy cost of walking (ECoW) in children with cerebral palsy (CP). Method In this prospective observational study, 12 children ... -
Fatigue. Hvordan kan vi som sykepleiere hjelpe pasienter med fatigue, slik at de får dekket sine grunnleggende behov?
