Rate-Dependent Avalanche Size in Athermally Sheared Amorphous Solids

Résumé

We perform an extensive numerical study of avalanche behavior in a two-dimensional Lennard-Jones glass at T=0, sheared at finite strain rates γ˙. From the finite size analysis of stress fluctuations and of transverse diffusion we show that flip-flip correlations remain relevant at all realistic strain rates. We predict that, in steady flow, the avalanche size scales as γ˙-1/d, with d the space dimension.
