Creep and high temperature fatigue performance of as buildselective laser melted Ti-based 6Al-4V titanium alloy
(Peer reviewed; Journal article, 2020)The present work focuses on the room and high temperature low-cycle fatigue and creep testing of Ti-6Al-4V manufactured by selective laser melting (SLM) or laser-based powder bed fusion process (LBPF). The fatigue specimens ... -
Digital Twin Based Condition Monitoring of a Knuckle Boom Crane: an Experimental Study
(Peer reviewed; Journal article, 2020)This paper presents a novel approach for implementation of a digital twin for condition monitoring of a small-scale knuckle boom crane. The digital twin of the crane is simulated real-time in a nonlinear finite element ... -
Energy-based ductile failure predictions in cracked friction-stir welded joints
(Peer reviewed; Journal article, 2019)This research aims to study the fracture behaviour in dissimilar aluminum alloys adjoined by friction stir welding (FSW). In this way, experimental data dealing with this topic was taken from the recent literature. In those ... -
Hydrogen stress cracking and crack initiation in precipitation hardened Ni-alloys
(Journal article; Peer reviewed, 2018)The two different precipitation hardened nickel alloys, Alloy 718 and Alloy 725, were tested in its as received condition. Their susceptibility to hydrogen stress cracking was examined by the use of stepwise increasing ... -
Learning from failures in cruise ship industry: The blackout of Viking Sky in Hustadvika, Norway
(Peer reviewed; Journal article, 2021)This article brings to attention learning from the failure - blackout, loss of propulsion and near grounding - of Viking Sky cruise ship which occurred in Hustadvika, Norway, in March 2019. Failures and accidents in the ... -
Learning from failures: Accidents of marine structures on Norwegian continental shelf over 40 years time period
(Peer reviewed; Journal article, 2020)This paper investigates accidents, major accidents and disasters which occurred on the Norwegian Continental Shelf (NCS) over a period of more than 40 years time (1972-2013). An accident investigation based on the system ... -
Rapid Strain Energy Density evaluation for V-notches under mode I loading conditions
(Peer reviewed; Journal article, 2020)This work investigates the possibility to evaluate the Strain Energy Density value with a free mesh model suggesting the use of a correcting formula a posteriori. Several numerical analyses were carried out to prove the ... -
Strain controlled medium cycle fatigue of a notched Pb-Sn-Cd lead alloy
(Journal article; Peer reviewed, 2019)During the extrusion process of subsea power cable sheathing layer it is possible that metallic and/or non-metallic debris present in the processing environment enter the metal lattice originating discontinuities that might ... -
Tooth flank fracture – An applied fatigue study of case hardened bevel gears
(Peer reviewed; Journal article, 2022)A material model for carburized CrNiMo steel and an advanced shear stress intensity, multiaxial fatigue criterion against surface and subsurface fatigue in bevel gears have been developed and presented in earlier publications. ...
