On the strength-ductility trade-off in thin blast-loaded steel plates with and without initial defects – An experimental study
(Peer reviewed; Journal article, 2022)An increase in material strength is commonly associated with better protection in blast-resistant design. However, higher material strength comes at the cost of reduced ductility, and it is still not clear how this trade-off ... -
ON THE SURFACING MECHANISM OF BUBBLE PLUMES FROM SUBSEA GAS RELEASE
(Chapter, 2017)A subsea release of gas poses a risk to humans and assets at the surface. Assessing this risk requires knowledge on how much gas reaches the surface and how it is distributed at the surface. This can be estimated by various ... -
On the temperature dependence of the cyclic compression behaviour of a thermoplastic vulcanizate elastomer
(Peer reviewed; Journal article, 2022)Effects of temperature on the uniaxial cyclic compression of a polypropylene based thermoplastic vulcanizate were studied in the range −40 °C–100 °C. The effect of temperature on the stress level was similar to that on the ... -
On the Temporal Stability of People’s Annoyance with Road Traffic Noise
(Peer reviewed; Journal article, 2020)Sixty‐one social surveys on annoyance caused by road traffic noise conducted world‐wide over a period of forty‐five years have been re‐analyzed by various means for possible temporal trends. Eighteen of these surveys ... -
On the Use of a Cluster Identification Method and a Statistical Approach for Analyzing Atom Probe Tomography Data for GP Zones in Al–Zn–Mg(–Cu) Alloys
(Peer reviewed; Journal article, 2023)Early-stage clustering in two Al–Mg–Zn(–Cu) alloys has been investigated using atom probe tomography and transmission electron microscopy. Cluster identification by the isoposition method and a statistical approach based ... -
On the use of random walk schemes in oil spill modelling
(Journal article; Peer reviewed, 2019-09)In oil spill models, vertical mixing due to turbulence is commonly modelled by random walk. If the eddy diffusivity varies with depth, failing to take the derivative of the diffusivity into account in the random walk scheme ... -
On the validity of the two-fluid-KTGF approach for dense gravity-driven granular flows as implemented in ANSYS Fluent R17.2
(Peer reviewed; Journal article, 2020)( Engelsk ) As a subproblem of solid transport in wellbores, we have investigated the cliff collapse problem by means of the Two-Fluid-Model (TFM), where the rheological description of the second phase (sand) is governed ... -
On the value of popular crystallographic databases for machine learning prediction of space groups
(Peer reviewed; Journal article, 2022)Predicting crystal structure information is a challenging problem in materials science that clearly benefits from artificial intelligence approaches. The leading strategies in machine learning are notoriously data-hungry ... -
On two speed optimization problems for ships that sail in and out of emission control areas
(Journal article; Peer reviewed, 2015)This paper deals with two speed optimization problems for ships that sail in and out of Emission Control Areas (ECAs) with strict limits on sulfur emissions. For ships crossing in and out of ECAs, such as deep-sea vessels, ... -
On weldability of aerospace grade Al-Cu-Li alloy AA2065 by wire-feed laser metal deposition
(Peer reviewed; Journal article, 2022)Al-Cu-Li alloys exhibit a superior strength to weight ratio, making the alloys attractive for applications within aviation and aerospace. However, their widespread application has been somewhat limited by the challenges ... -
On-board Live Storage of Atlantic Cod (Gadus morhua): Effects of Capture Stress, Recovery, Delayed Processing, and Frozen Storage on Fillet Color Characteristics
(Journal article; Peer reviewed, 2019-11-11)On-board live storage of Atlantic cod caught by trawl was evaluated as a potential method to improve the color characteristics of fillets. Before slaughter and processing, the fish were: (i) stored live for 3–6 h, (ii) ... -
On-Bottom Stability Analysis of Subsea Pipelines Under Combined Irregular Waves and Currents
(ASME Proceedings | Pipelines, Risers, and Subsea Systems;OMAE2017-61363, Chapter, 2017-06-25)The objective of the paper is to study the effect of different parameters regarding on-bottom stability of subsea pipelines under combined irregular waves and currents. The effect of friction coefficient is first investigated. ... -
