Probing microplasticity in small scale FCC crystals via Dynamic Mechanical Analysis [PDF]

open access: yes, 2016
In small-scale metallic systems, collective dislocation activity has been correlated with size effects in strength and with a step-like plastic response under uniaxial compression and tension.

Thermal-hydraulic simulation and evaluation of a natural circulation thermosyphon loop for a reactor cavity cooling system of a high-temperature reactor

open access: yesNuclear Engineering and Technology, 2020
The investigation into a full-scale 27 m high, by 6 m wide, thermosyphon loop. The simulation model is based on a one-dimensional axially-symmetrical control volume approach, where the loop is divided into a series of discreet control volumes.

Extreme Wave Loading on a Vertical Circular Cylinder

open access: yesApplied Sciences, 2023
Extreme wave loading on a marine structure, consisting of a quasi-static and a dynamically slamming component, often drives the design of such a structure. Their accurate predictions remain challenging tasks. This paper examines the slamming contribution

Implementation of Temporal Parallelization for Rapid Quasi-Static Time-Series (QSTS) Simulations

open access: yes2019 IEEE 46th Photovoltaic Specialists Conference (PVSC), 2019
Quasi-static time-series (QSTS) analysis of distribution systems can provide critical information about the potential impacts of high penetrations of distributed and renewable resources, like solar photovoltaic systems. However, running high-resolution yearlong QSTS simulations of large distribution feeders can be prohibitively burdensome due to long ...

A Bayesian Dynamic Method to Estimate the Thermophysical Properties of Building Elements in All Seasons, Orientations and with Reduced Error

open access: yesEnergies, 2018
The performance gap between the expected and actual energy performance of buildings and elements has stimulated interest in in-situ measurements. Most research has employed quasi-static analysis methods that estimate heat loss metrics such as U-values ...

Compressive mechanical behavior and model of composite elastic-porous metal materials

open access: yesMaterials Research Express, 2021
This work presents the experimental characterization and theoretical modeling of composite elastic-porous metal materials (C-EPMM). C-EPMM is a novel porous metallic damping material made of wire mesh and wire helix.

Experimental study and numerical modelling of woven fabric kenaf fiber composites hybrid adhesively bonded-bolted joints [PDF]

open access: yes, 2018
Couple with natural fiber composite parts, hybrid joints provide better joint strength than using separate joints. There are limited studies on structures response and strength prediction work on hybrid joints that limits its applicability.

Motivation and requirements for quasi-static time series (QSTS) for distribution system analysis

open access: yes2017 IEEE Power & Energy Society General Meeting, 2017
Distribution system analysis with ever increasing numbers of distributed energy resources (DER) requires quasistatic time-series (QSTS) analysis to capture the time-varying and time-dependent aspects of the system. Previous literature has demonstrated the benefits of QSTS, but there is limited information available for the requirements and standards ...

A new technique for observationally derived boundary conditions for space weather

open access: yesJournal of Space Weather and Space Climate, 2018
Context. In recent years, space weather research has focused on developing modelling techniques to predict the arrival time and properties of coronal mass ejections (CMEs) at the Earth.

Time delay in the strong field limit for null and timelike signals and its simple interpretation

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Gravitational lensing can happen not only for null signals but also timelike signals such as neutrinos and massive gravitational waves in some theories beyond GR.
