HEAs are loosely defined as solid solution alloys that contain more than five principal …

Modeling the mechanics of amorphous solids at different length scale and time scale

D Rodney, A Tanguy… - Modelling and Simulation …, 2011 - iopscience.iop.org
We review the recent literature on the simulation of the structure and deformation of
amorphous solids, including oxide and metallic glasses. We consider simulations at different …

Scale-free intermittent flow in crystal plasticity

DM Dimiduk, C Woodward, R LeSar, MD Uchic - Science, 2006 - science.org

Scale invariance in plastic flow of crystalline solids

M Zaiser - Advances in physics, 2006 - Taylor & Francis
From the traditional viewpoint of continuum plasticity, plastic deformation of crystalline solids
is, at least in the absence of so-called plastic instabilities, envisaged as a smooth and quasi …

Statistics of dislocation slip avalanches in nanosized single crystals show tuned critical behavior predicted by a simple mean field model

N Friedman, AT Jennings, G Tsekenis, JY Kim, M Tao… - Physical review …, 2012 - APS
We show that slowly sheared metallic nanocrystals deform via discrete strain bursts (slips),
whose size distributions follow power laws with stress-dependent cutoffs. We show for the …

Athermal mechanisms of size-dependent crystal flow gleaned from three-dimensional discrete dislocation simulations

SI Rao, DM Dimiduk, TA Parthasarathy, MD Uchic… - Acta Materialia, 2008 - Elsevier
Recent experimental studies have revealed that micrometer-scale face-centered cubic (fcc)
crystals show strong strengthening effects, even at high initial dislocation densities. We use …

Power laws are omnipresent and actively studied in many scientific fields, including plasticity
of materials. Here, we report the power-law statistics in the second and subsequent pop-in …

Avalanches and plastic flow in crystal plasticity: an overview

S Papanikolaou, Y Cui, N Ghoniem - Modelling and Simulation in …, 2017 - iopscience.iop.org
Crystal plasticity is mediated through dislocations, which form knotted configurations in a
complex energy landscape. Once they disentangle and move, they may also be impeded by …
