It has been widely accepted that the plastic events of amorphous solids after mechanical
yield belong to a highly correlated avalanche state. However, whether the plastic events …

Widespread processes in nature and technology are governed by the dynamical transition
whereby a material in an initially solid-like state, whether soft or hard, then yields. Major …

Amorphous solids increase their stress as a function of an applied strain until a mechanical
yield point whereupon the stress cannot increase anymore, afterward exhibiting a steady …

We present results on a series of two-dimensional atomistic computer simulations of
amorphous systems subjected to simple shear in the athermal, quasistatic limit. The …

Yield stress materials flow if a sufficiently large shear stress is applied. Although such
materials are ubiquitous and relevant for industry, there is no accepted microscopic …

Using numerical simulations, we perform an extensive finite-size analysis of the transverse
diffusion coefficient in a sheared 2D amorphous solid over a broad range of strain rates at …

Plastic yielding of amorphous solids occurs by power-law distributed deformation
avalanches whose universality is still debated. Experiments and molecular dynamics …

Brittle materials exhibit sharp dynamical fractures when meeting Griffith's criterion, whereas
ductile materials blunt a sharp crack by plastic responses. Upon continuous pulling, ductile …

We discuss avalanche and finite-size fluctuations in a mesoscopic model to describe the
shear plasticity of amorphous materials. Plastic deformation is assumed to occur through …

We investigate numerically the yielding transition of a two-dimensional model amorphous
solid under external shear. We use a scalar model in terms of values of the total local strain …
