Fatigue life estimation of existing steel structures under time-dependent structural degradation
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-30)The purpose of this thesis is to present a method to estimate remaining fatigue life of steel bridge members subjected to time-dependent corrosion. This method contributes to the further development of the theoretical ... -
Fatigue life estimation of tubular joints in offshore jacket according to the SCFs in DNV-RP-C203, with comparison of the SCFs in ABAQUS/CAE
(Master thesis, 2014-06-13)Mostly offshore platform installed in shallow water, less than 300 meters for drilling and production of oil and/or gas are normally fixed to seabed and constructed as truss framework with tubular members as structure ... -
Fatigue of service pipes
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)The first part of this thesis will present the principle of fatigue, vibration and damping of service pipes on the Norwegian continental shelf. Thus us used for the creation of a screening methodology for prioritizing ... -
Fatigue of Structural and Additively Manufactured Steels: Damage Assessment and Modelling Techniques
(PhD thesis UiS;, Doctoral thesis, 2022-09)The topics of damage assessment by in situ measurements before a macroscopic crack has been initiated, nonlinear damage modelling and additive manufacturing are herein discussed and researched from the perspective of the ... -
Fatigue reliability assessment of ageing railway truss bridges: Rationality of probabilistic stress-life approach
(Journal article; Peer reviewed, 2016-05)Rail authorities all over the world are paying attention to extend the service lives of railway bridges. The famous Miner’s rule employed deterministic or probabilistic fatigue assessment approaches are generally used to ... -
Fatigue Strength Curve for Tubular Joints of Offshore Structures under Dynamic Loading
(Journal article, 2021)Abstract Offshore structures are subjected to dynamic environmental loads (wave and wind loads). A stress-life fatigue strength curve is proposed for tubular joints which are in the splash zone area of offshore jacket ... -
Fatigue strength degradation of corroded structural details: A formula for S‐N curve
(Peer reviewed; Journal article, 2019)A formula is proposed to predict fatigue strength of corroded members and joints of steel structures. The concept of the formula is first studied from recently identified mechanism of corrosion fatigue. Hence, the corresponding ... -
Fatigue strength degradation of metals in corrosive environments
(Journal article; Peer reviewed, 2017)Structures exposed to aggressive environmental conditions are often subjected to time-dependent loss of coating and loss of material due to corrosion; this causes reduction in the cross-sectional properties of the members, ... -
Fatigue study of conductor at the conductor guides’ levels on the EKOFISK-K platform
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)This master thesis presents the method & results from a fatigue study of conductor at the conductor guides’ levels & static and dynamic hydrodynamic analysis of a 20’’ conductor installed on the Ekofisk-K platform using ... -
Fatigue: a frequent and biologically based phenomenon in newly diagnosed celiac disease
(Peer reviewed; Journal article, 2022)Fatigue is increasingly recognized as a major complaint in patients with chronic inflammatory and autoimmune diseases. Although fatigue is assumed to represent a significant problem in celiac disease, existing knowledge ... -

Fault Activity Control on Upper Jurassic-Early Cretaceous Wedges in the Snorre Fault Block and its Surrounding Area
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-07)In this study, the question” how fault activity controlled the infill and geometry of the Upper Jurassic-Lower Cretaceous wedges in the Snorre Fault Block and surrounding area” is addressed. To achieve the goal, three-dimensional ... -
Fault controlled sedimentation: A case study of the Kerpini fault, Greece
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)The study area is located in Gulf of Corinth, Central Grecee. The focus of the study is located in the Kerpini area. The objective of this study is to learn about fault controlled sedimentation which is related to their ... -
Fault Displacement Analysis in the Kalavryta Region of the Corinth Rift System, Greece.
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06-15)The Corinth Rift of Central Greece is one of the world’s most active rifts. Regional N-S extension has resulted in a series of half-grabens within a system of uplifted, rotated and north-dipping normal faults. Extensive ... -
Fault-Tolerant Control Based on Virtual Actuator and Sensor for Discrete-Time Descriptor Systems
(Peer reviewed; Journal article, 2020)This article proposes a fault-tolerant control (FTC) strategy based on virtual actuator and sensor for discrete-time descriptor systems subject to actuator and sensor faults. The fault-tolerant closed-loop system, which ... -
Faulty screen time measures hamper national policies: here is a way to address it
(Peer reviewed; Journal article, 2023)Following widespread reliance on online interactions during COVID-19, Western governments are strategizing and launching new plans for children's use of screens. It is healthy to debate, for example, the ethics of artificial ... -
Faunal and Microbial Sediment Community Disturbances Caused by Organic and Inorganic Contamination
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06)There are ongoing developments to enable treatment of oil based drill cuttings with subsequent deposition offshore rather than the current practice to transport and treat such material on land. A sample from a step in the ...
