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 ... -

(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
(Master thesis, 2022)A study of the stress rupture time of glass fiber epoxy composite laminates in humid environments was investigated. Test specimens were made in order to compare the failure time of a saturated and non-saturated specimen ... -
