Internal clearance behaviour in healthy and faulty bearings
(Peer reviewed; Journal article, 2023)Internal clearance is a critical parameter in bearing design and operation because it affects the bearing's performance. It can be considered as a special type of the looseness fault. Several studies indicate that rolling ... -
Internal Corrosion Damage Mechanisms of the Underground Water Pipelines
(Peer reviewed; Journal article, 2022)Internal water pipe corrosion is a complicated problem due to the interaction of water quality parameters with pipe wall. This study presents investigations of internal pipe surface corrosion mechanisms related to water ... -
Investigating Effects of Fused-Deposition Modeling (FDM) Processing Parameters on Flexural Properties of ULTEM 9085 using Designed Experiment
(Journal article; Peer reviewed, 2018-03)Fused-deposition modeling (FDM), one of the additive manufacturing (AM) technologies, is an advanced digital manufacturing technique that produces parts by heating, extruding and depositing filaments of thermoplastic ... -
Investigating the effect of Molybdenum on Pitting Corrosion Resistance of type AISI 316L Stainless Steel in Seawater
(Master thesis, 2021)This master thesis focuses on how long it is possible to expose AISI 316L stainless steel to seawater before pitting corrosion occurs. Exposure time is of interest because seawater ingress can cause pitting corrosion in ... -
Investigation of condition based maintenance practice within Norwegian oil and gas
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)The Oil and Gas industry’s increasing demands within risk management, cost efficiency, plant availability and the technology development have led to an increased interest for monitoring of equipment for performance and ... -
Investigation of Corrosion Resistance of Duplex, Lean Duplex and Austenitic Stainless Steels in Simulated Offshore Environment
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)Some duplex grades are developed to replace the 300 series of austenitic stainless steels in harsh chloride applications due to superior mechanical and corrosive properties. Since the market price for nickel and molybdenum ... -
Investigation of critical time and temperature for pitting corrosion on 316SS cladding
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06-30)The austenitic stainless steel 316L is a very common and low carbon stainless steel grade. 316L has great corrosion characteristics under harsh conditions such as seawater, acidic medias etc. The presence of molybdenum ... -
Investigation of Influence of Adjustments in Cyclist Arm Position on Aerodynamic Drag Using Computational Fluid Dynamics
(Peer reviewed; Journal article, 2020-06)In professional cycling, even small adjustments in position could mean that valuable seconds are gained over the course of a time-trial race. This study investigates the influence of arm position on the aerodynamic drag ... -
Investigation of Material Property changes in HSLA Steel due to Weld Proximity
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-09-15)Standards and specifications apply a rule of thumb when determining the distance of two adjacent weld joints, but they rarely give any clear technical justification for the predetermined values. It is vital to understand ... -
Investigation of materials which reduce CO2 in long term.
(Bachelor thesis, 2021)About one quarter of global energy use is for production of materials. The more efficient we are in the use of these materials, the better it is for the long-term reduction of CO2 and other GHG emissions. Concrete is the ... -
