Low cycle fatigue behavior of additively manufactured Ti-6Al-4V under non-proportional and proportional loading
(Journal article; Peer reviewed, 2019)Experimental tests were conducted on additive manufactured Ti-6Al-4V titanium alloy to investigate the mechanical and crack properties under multiaxial cyclic loading. Selective Laser Sintering technique (SLS) was employed ... -
Low cycle fatigue life prediction of 10CrNi3MoV steel and undermatched welds by damage mechanics approach
(Peer reviewed; Journal article, 2021)Welding of steel is a technique frequently used in practical engineering applications; however, their mechanical performance is strongly dependent on the physical metallurgical status of the weldments. In the present study, ... -
Low cycle fatigue of bolted connections in composites for arctic applications
(Master thesis, 2011)Nowadays composite materials are a very interesting research field. They show an extraordinary performance due to their high stiffness and low density. They are applied in high advance technology industries such as aerospace ... -
Low-cost Navigation and Collision Avoidance System
(Master thesis, 2020)Ettersom teknologien rundt autonome bakke-kjøretøy (AGV’er) stadig er i utvikling, trenger man også mer datakraft for å realisere disse systemene. Samtidig er lav-kost ettkorts datamaskiner (SBC’er) med høy ytelse blitt ... -
A low-cost predictive display for teleoperation: Investigating effects on human performance and workload
(Peer reviewed; Journal article, 2020)Teleoperation in an environment with latency is difficult and highly stressful for human operators, resulting in high cognitive workload and decreased human performance. This work investigates if a simple predictive display ... -
Low-cost tooling concept for customized tube bending by the use of additive manufacturing
(Peer reviewed; Journal article, 2023)Bending is commonly used in the manufacturing of finished and semi-finished, profilebased products. However, costly profile and bend geometry dependent tooling hampers its applicability for low volume production or ... -
Low-cost tooling concepts for customized tube bending processes using hybrid design and additive manufacturing
