On the Joint Distribution of Excursion Duration and Amplitude of a Narrow-Band Gaussian Process
(Journal article; Peer reviewed, 2018)The probability density of crest amplitude and duration that exceeds a given level is used in many theoretical and practical problems in engineering that are subjected to fluctuating loads such as wind and wave loads. The ... -
On the levelised cost of energy of windfarms
(Journal article; Peer reviewed, 2020)As windfarms spread, so have the discussions concerning their economics. Some argue from a basic definition of Levelised Cost of Energy (LCOE), that wind energy is more cost effective than other energy sources. The opponents ... -
On the long-term correlations in the twinning and dislocation slip dynamics
(Peer reviewed; Journal article, 2020)The present work aims at gaining new insights into the dynamics of the dislocation slip and twinning processes, which govern the majority of possible scenarios of plastic deformation in structural metals and alloys. Using ... -
On the low reinforcing efficiency of carbon nanotubes in high-performance polymer fibres
(Peer reviewed; Journal article, 2021)Driven by the exceptionally high mechanical properties of carbon nanotubes (CNTs), over the years an extensive research effort has been devoted to the reinforcement of high-performance polymer fibres with CNTs. However, ... -
On the Material Characterization of an Aluminium Alloy Using Different Specimens and Identification Methods
(Journal article; Peer reviewed, 2018)The validity of material properties obtained from uniaxial tension tests using different specimen types and measurement techniques is investigated in this paper. Four different specimen geometries were tested, including ... -
On the mathematics of higher structures
(Journal article; Peer reviewed, 2019)In a series of papers, we have discussed higher structures in science in general, and developed a framework called hyperstructures for describing and working with higher structures. We discussed the philosophy behind higher ... -
On the Mechanical Energy Involved in the Catastrophic Rupture of Liquid Hydrogen Tanks
(Peer reviewed; Journal article, 2022)Hydrogen can play a central role in the energy transition thanks to its unique properties. However, its low density is one of the main drawbacks. The liquefaction process can drastically increase its density up to virtually ... -
On the mechanical integrity of AA6082 3D structures deposited by hybrid metal extrusion & bonding additive manufacturing
(Peer reviewed; Journal article, 2020)Hybrid Metal Extrusion and Bonding Additive Manufacturing (HYB-AM) is a new solid-state process for the production of 3D metal structures. In HYB-AM, the wire feedstock is continuously processed through an extruder and ... -

On the mechanisms of charge weld evolution in aluminum extrusion
(Journal article; Peer reviewed, 2024)This study aims to provide new insights into the governing mechanisms of material property evolution within the charge weld zone in the hot extrusion process of aluminum profiles. A set of 6xxx series aluminum alloy tubular ... -
On the mechanisms of consumption of calcium lignosulfonate by cement paste
(Journal article; Peer reviewed, 2017)The aim of this paper is to assess the mechanisms of consumption of softwood calcium lignosulfonate (LSs) by cement paste. The LSs consumption by two different cements (CX and ANL) and two reference materials (CaCO3 and ... -
On the microscopic modeling of vehicular traffic on general networks
(Peer reviewed; Journal article, 2020)We introduce a formalism to deal with the microscopic modeling of vehicular traffic on a road network. Traffic on each road is unidirectional, and the dynamics of each vehicle is described by a follow-the-leader model. ... -
On the microstructural origins of improvements in conductivity by heavy deformation and ageing of Al-Mg-Si alloy 6101
(Peer reviewed; Journal article, 2021)This work has examined an Al-0.54Mg-0.38Si (at.%) conductor alloy (6101) subjected to two different thermomechanical processing routes. Conventional solution treatment, quenching, and artificial ageing (170 °C) was compared ... -
