Rheology and printability of cement paste modified with filler from manufactured sand
(Chapter, 2024)Manufactured sand is increasingly used in concrete production. We study the effects of substituting parts of the binder with manufactured filler (particle size 0.04 - 0.250 mm) on the printability of cement paste experimentally ... -
Revealing the critical pore size for hydrogen storage via simultaneous enclathration and physisorption in activated carbon
(Peer reviewed; Journal article, 2024)Hydrogen hydrate is regarded as an ideal hydrogen storage medium, but it faces unsolved challenges related to its extreme formation and stabilization conditions. Recent experiments have demonstrated that utilizing porous ... -
Crack growth in high strength mooring line steel under variable amplitude loading
(Peer reviewed; Journal article, 2024)Mooring lines are of key importance for the safe and reliable operation of numerous floating offshore structures. Due to the constantly changing wind and wave conditions acting on such structures, any fatigue crack growth ... -
Representation-theoretical characterization of canonical custodial symmetry in NHDM potentials
(Journal article; Peer reviewed, 2024)By considering the basis-covariant constituents of N-Higgs-doublet potentials, we derive necessary and sufficient conditions for canonical SO(4)_C Custodial Symmetry (CS) of potentials with N>2 doublets, based on ... -
An Experiential Learning Opportunity in Norway: Computation for Bioengineering and Mechanical Engineering Students
(Journal article; Peer reviewed, 2024)The global learning initiative at Northeastern University is focused on fostering intercultural communication skills. The Dialogue of Civilization (DOC) program serves as a mechanism to achieve such a goal by offering ... -

Repair Options for Corrosion-damaged Prestressed Concrete Structures
(Peer reviewed; Journal article, 2024)Prestressing of bridges allows construction of long spanned bridges made from thin structural members with high flexural and shear capacity. Studies have shown that some of the existing prestressed bridges are not meeting ... -
Unraveling Ice–Solid Interface Rupture Dynamics: Insights from Molecular Dynamics Simulations
(Peer reviewed; Journal article, 2024)Unwanted icing on exposed surfaces poses significant risks, driving the quest for effective anti-icing mechanisms. While fracture mechanics concepts have been developed for designing coatings that weaken the ice–solid ... -
Aluminium nodes for timber gridshells: Parametric detailing of node principles
(Peer reviewed; Journal article, 2023)Gridshell nodes are key elements regarding structural performance, visual appearance and assembly of any gridshell that have been given little attention in recent research. This paper explores aluminium as a material for ... -
Carbonation and corrosion of steel in fly ash concrete, concluding investigation of five-year-old laboratory specimens and preliminary field data
(Journal article; Peer reviewed, 2024)Carbonation development and reinforcement corrosion were investigated on concretes exposed for a five-year period at 90% RH, 20 ℃, and 5% CO2, and for a six-year period at natural carbonation. Portland cement-based binders ... -
Numerical benchmark for road bridge damage detection from passing vehicles responses applied to four data-driven methods
(Journal article; Peer reviewed, 2024)Drive-by bridge monitoring utilizes measured responses from passing vehicles to perform damage detection of bridge, a methodology challenged by multiple factors and operational conditions. Recently, data-driven methods ... -
Atomistic scale thermal transport in metal and polymer
(Doctoral theses at NTNU;2024:276, Doctoral thesis, 2024)The never-ending need for faster, more complex devices has started a trend of miniaturization that has dominated the electronic industry since the 60s. This trend has led to the characteristic dimensions of components going ... -
Automatic Methods for Modal- Based Structural Health Monitoring
(Doctoral theses at NTNU;2024:229, Doctoral thesis, 2024)It is necessary to know the actual state of a structure to ensure its safe continued operation. Structural health monitoring can provide this information, given a monitoring network of sensors on the structure. A prompt ... -
Phase-field models for ductile fracture. Stress triaxiality dependent approaches applied to pipeline steel
(Doctoral theses at NTNU;2024:247, Doctoral thesis, 2024)Ductile fracture is associated with plastic deformation and the development of voids in the material, which leads to a gradual fracture evolution. Ductile fracture in metals is of great importance as it can occur in large ... -
Uncertainty quantification and sensitivity analysis of vascular hemodynamics. Application to the common carotid artery
(Doctoral theses at NTNU;2024:235, Doctoral thesis, 2024)Cardiovascular diseases have been the leading cause of death globally for the past decades. Many cardiovascular diseases are a result of structural changes in the arterial wall, which modify its stiffness. Thus, arterial ... -
