Corrosion properties of AA5083 and AA6082 in seawater - effect of temperature, pH and potential
(Master thesis, 2016)Aluminium is an interesting material for use in subsea structures due to its low weight. So called corrosion resistant aluminium alloys from the Al-Mg (5xxx)- and Al-Mg-Si (6xxx) series have been used for many years in ... -
Corrosion Properties of Stainless Steel in Stagnant Seawater
(Master thesis, 2020)Denne rapporten fokuserer på korrosjonsegenskapene til rustfritt stål i stillestående sjøvann i åpne og lukkede beholdere. I flere tiår har ulike legeringer av rustfritt stål blitt brukt i marint miljø på grunn av ... -
Corrosion Properties of Stainless Steels Exposed to Sodium Chloride and Small Addition of Fluoride
(Master thesis, 2019)Formålet med denne oppgaven var å undersøke hvilken effekt fluorider og klorider har på gropkorrosjon av ulike rustfrie stål. Denne rapporten vurderer kritiske faktorer som temperatur kombinert med ulik konsentrasjon av ... -
Corrosion Protection under Thermal Insulation
(Master thesis, 2013)Corrosion under insulation (CUI) is an extensive and costly problem for the petrochemical and chemical industry. Both good coatings to mitigate the problem and test methods to ensure the quality of these coatings are needed. ... -
Corrosion, hydrogen uptake and environmentally assisted cracking of flexible pipe steel armour wires
(Doctoral theses at NTNU;2022:159, Doctoral thesis, 2022)Flexible pipes are widely used in oil and gas applications. They consist of several metallic and polymeric layers, including a layer of tensile armour wires made from high-strength carbon steels. The armour wires are closely ... -
Cost and Quality Consequences of Shortening the Project Life Cycle
(Master thesis, 2013)Shortening duration of project is a challenging task. If time is reduced with no attention is paid to additional risk, not only no time reduction is achieved but also it can exert counter effect by increasing the time, ... -
Cost modelling of onboard cobot-supported item sorting in a picking system
(Peer reviewed; Journal article, 2020)For manual picking processes in warehouses and assembly line feeding, collaborative robots – cobots – hold a potential to support operators and, thereby, enhance performance. However, studies focused on the economic aspects ... -
A coupled elastoplastic damage model for brittle rocks
(Peer reviewed; Journal article, 2020)Brittle rock contains an important plastic deformation, which causes microcracks when coupled with stress-induced damage. A new coupled elastoplastic damage model is established in order to discuss the damage behaviors ... -
Coupled Fluid Flow and Elastoplastic Damage Analysis of Acid Stimulated Chalk Reservoirs
(Doctoral thesis at NTNU;2015:223, Doctoral thesis, 2015) -
Coupling AltaRica models with optimization heuristics for the assessment of maintenance policies
(Master thesis, 2018)The main objective of this thesis is do maintenance optimization for a system using AltaRica simulation tools. Maintenance optimization is based on the assessment of maintenance policy. Stochastic simulation is applied to ... -
Crack initiation life in notched Ti-6Al-4V titanium bars under uniaxial and multiaxial fatigue: Synthesis based on the averaged strain energy density approach
(Journal article; Peer reviewed, 2017)The fatigue behaviour of circumferentially notched specimens made of titanium alloy, Ti-6Al-4V, has been analysed. To investigate the notch effect on the fatigue strength, pure bending, pure torsion and multiaxial ... -
Crack paths in multiaxial fatigue of C45 steel specimens and correlation of lifetime with the thermal energy dissipation
(Peer reviewed; Journal article, 2022)The work reports the observed fatigue damage of C45 steel specimens tested in a previous work under multiaxial loading conditions and its relationship with the thermal energy dissipation which has been used in the last ... -
Crack propagation and arrest of structural steels and pipelines
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:105, Doctoral thesis, 2008)Crack arrest of fast running cracks is an important issue for the safety of steel structures. Crack arrest design can prevent fatal damage of large structures by restricting the influence of the incidents. Therefore crack ... -
Crack propagation in a brittle DCB specimen assessed by means of the Williams? power expansion
(Journal article; Peer reviewed, 2019)A double cantilever beam geometry has been chosen in order to investigate the importance of the higher-order terms of the Williams’ power expansion for the crack path estimation. The crack propagation has been tested ... -
Cracked components under anti-plane loading: Recent outcomes and future developments
(Journal article; Peer reviewed, 2017)The existence of three-dimensional effects at cracks has been known for many years, but understanding has been limited, and for some situations still is. Understanding improved when the existence of corner point singularities ... -
Cracking Behaviors of Rock-Like Specimens Containing Two Sets of Preexisting Cross Flaws under Uniaxial Compression
(Journal article; Peer reviewed, 2019)Cross flaws occur widely in rock masses and play a crucial role in the failure of rock engineering. This article first experimentally studies the cracking behaviors of rock-like specimens containing two sets of preexisting ... -
Crane load position control using Lyapunov-based pendulum damping and nonlinear MPC position control
(Chapter, 2019)A crane control system is presented where the crane load can track a position trajectory with ultimately bounded pendulum motions of the load. This is done with an inner loop using a Lyapunov-based damping controller which ... -
