Literature Review and Statistical Analysis of Assembly Line Characteristics in Assembly System Design
(Master thesis, 2020)Monteringslinjer er kostnadseffektive produksjonssystemer som setter sammen deler til ferdige produkter. På grunn av endring i kundemønster tvinges flere monteringslinjer til å tilpasse seg, fra masseproduksjon av ... -
Litjfossen Pumpekraftverk (KVO) - Utnytting av prisvariasjoner i Midt-Norge
(Master thesis, 2016)Det norske kraftmarkedet er i endring. Aktiv handel, større mengde uregulert kraftproduksjon og bedre tilknytning til andre Europeiske land fører til at volatiliteten i kraftprisene øker. Med dagens utvikling og store ... -
Load Deflection Characteristics of Guide Vane End Seals
(Master thesis, 2017)This Master Thesis consider the load deflection characteristics of end seals incorporated in guide vanes used in hydropower turbines. The force response of the end seals is critical in order to prevent leakage and thus ... -
Local bracer vibrations for Offshore Wind jackets
(Master thesis, 2013)During the course of this master project, the candidates have worked with FEA of local vibrations occurring in bracers on offshore windturbine jacket. These vibrations arise as a dynamic response from wind-, wave-, and ... -
Local mechanical properties and precipitation inhomogeneity in large-grained Al–Mg–Si alloy
(Peer reviewed; Journal article, 2022)Al–Mg–Si (6xxx series) alloys show excellent mechanical properties due to the precipitates formed during heat treatment. However, heat treatment of these alloys results in a soft precipitation free zone (PFZ) close to grain ... -
Local strain energy based fatigue assessment of cruciform welded joints: experimental data analysis and influence of hot-dip galvanization
(Journal article; Peer reviewed, 2018)Performing the fatigue assessment of a welded joint using the Notch Stress Intensity Factors [1] presents two major challenges. The first is the necessity of a precise reconstruction of the stress field around the notch ... -
Local strain energy density for the fatigue assessment of hot dip galvanized welded joints: Some recent outcomes
(Journal article; Peer reviewed, 2017)Since in literature only data about the effect of the hot-dip galvanizing coating on fatigue behavior of unnotched specimens are available, whereas very few for notched components and none for welded joints, the aim of ... -
Local strain energy density for the fracture assessment of polyurethane specimens weakened by notches of different shape
(Journal article; Peer reviewed, 2017)Recent studies on local stress fields in proximity of crack and notch tips have shown that Strain Energy Density (SED), averaged in a circular control volume surrounding the point of stress singularities, represents a ... -
Local strain energy density to assess the multiaxial fatigue strength of titanium alloys
(Peer reviewed; Journal article, 2016)The present paper investigates the multiaxial fatigue strength of sharp V-notched components made of titanium grade 5 alloy (Ti-6Al-4V). Axisymmetric notched specimens have been tested under combined tension and torsion ... -
Localized wrinkling of metal films on elastic and liquid substrates
(Peer reviewed; Journal article, 2019)Global and localized wrinkling phenomena in films/substrates have been widely studied by means of experiment and theoretical analyses in the past two decades. They have shown broad application prospect in microstructure ... -
Logistics 4.0 Technologies Driven Approaches for Warehouse Operations: A Framework of Resource Management System
(Doctoral theses at NTNU;2017:267, Doctoral thesis, 2017)The last several years have seen the evolution of warehouse from stockpiling of inventory to high-velocity operations, allowing facilities to handle as many goods as they typically deal with, but at lower costs. Warehouses ... -
Logistics and Supply Chain in Circular Economy and Several Solutions for Norwegian Personal Clothing “Analyzing and Mapping Norway's Private (Personal) Clothing: Applying Circular Economy Principles, A Logistics Perspective on Current Practices and Improvements.”
(Master thesis, 2024)In order to address the growing worldwide issue of resource depletion and environmental effects, this thesis investigates the crucial shift that Norway's private clothing system are making towards a circular economy. Since ... -
Logistics Planning Module for Microsoft AX: Demand Planning
(Master thesis, 2012)One could hardly find a person who would disagree that the information technology is essential part of any business today. In the same way it is known how a proper demand planning process can assist an organization in ... -
Logistics Planning Module for Microsoft Dynamics AX: Supply Chain Order Management
(Master thesis, 2011)This thesis presents a solution for supply chain order management to complement traditional ERP planning functionality. Challenges and possibilities of today’s planning solutions are presented, and ERP system functionality ... -
Logistikkplanleggingsmodul for Microsoft Dynamics AX: Lagerplanlegging
(Master thesis, 2011)Bedrifter i dagens industri presses stadig til å levere raskere og bedre produkter til en lavere pris gjennom effektiv koordinering av produksjon og distribusjon. Riktig styring av lagernivå vil i denne sammenheng kunne ... -
Long term material properties of pressure vessels made of composite material
(Doctoral theses at NTNU;2022:56, Doctoral thesis, 2022)Pressure vessels are currently the limiting factor in the hydrogen distribution chain. The pressure vessels are preferably made out of composite materials to achieve practical weight to strength ratios and avoid hydrogen ... -
Long Term Properties of Composites and Polymers
(Master thesis, 2023)Kompositt- og polymermaterialer brukes i offshore og maritim industri, men data angående deres ytelse etter langvarig eksponering for miljøet er begrenset. Dette er hovedsakelig på grunn av mangel på testede data vedrørende ... -
Long Term Properties of Glass Fiber Epoxy Laminates in Dry and Humid Environment
