Backward correlations and dynamic heterogeneities: a computer study of ion dynamics
, 2002 We analyse the correlated back and forth dynamics and dynamic heterogeneities, i.e. the presence of fast and slow ions, for a lithium metasilicate system via computer simulations.

Intermittent electron density and temperature fluctuations and associated fluxes in the Alcator C-Mod scrape-off layer [PDF]
, 2018 The Alcator C-Mod mirror Langmuir probe system has been used to sample data time series of fluctuating plasma parameters in the outboard mid-plane far scrape-off layer. We present a statistical analysis of one second long time series of electron density,

Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves
Advanced Engineering Materials, EarlyView.Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.

Molecular Dynamics Computer Simulation of the Dynamics of Supercooled Silica
, 1997 We present the results of a large scale computer simulation of supercooled silica. We find that at high temperatures the diffusion constants show a non-Arrhenius temperature dependence whereas at low temperature this dependence is also compatible with an

Rheological Master Curves of Crystallizing Polymer Mixtures
Applied Rheology, 2006 We present a simple methodology for extending linear viscoelastic measurements of crystallizing polymers to the high-frequency regime, where usually crystallization kinetics represents an obstacle. The idea is to perform rapid quenches, below the melting

Advanced Engineering Materials, EarlyView.A study of mechanical properties and fractography of PBF‐LB/M‐built Inconel 718, performing heat treatments and hot‐isostatic pressing, is presented. Ultimate tensile strength and fatigue behavior are evaluated, examining differences in maximum load behavior, elongation, and regimes of fatigue.

Damage detections in nonlinear vibrating thermally loaded plates [PDF]
, 2009 In this work, geometrically nonlinear vibrations of fully clamped rectangular plates subjected to thermal changesare used to study the sensitivity of some vibration response parameters to the presence of damage and elevated temperature. The geometrically

Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Formulation of non-linear viscoelastic–viscoplastic constitutive equation for polyamide 6 resin
Heliyon, 2021 In this study, a non-linear viscoelastic–viscoplastic constitutive equation for polyamide 6 (PA6) is formulated and a new model is suggested for the viscoplastic part of the equation.
