The deformation and flow of disordered solids, such as metallic glasses and concentrated
emulsions, involves swift localized rearrangements of particles that induce a long-range …

The aim of this article is to discuss the concepts of non-local rheology and fluidity, recently
introduced to describe dense granular flows. We review and compare various approaches …

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 …

We present the experimental and numerical studies of a two-dimensional sheared
amorphous material composed of bidisperse photoelastic disks. We analyze the statistics of …

Under external mechanical loading, glassy materials, ranging from soft matter systems to
metallic alloys, often respond via formation of inhomogeneous flow patterns, during yielding …

The elastic coupling between plastic events is generally invoked to interpret plastic
properties and the failure of amorphous soft glassy materials. We report an experiment …

We study the stability of amorphous solids, focussing on the distribution P (x) of the local
stress increase x that would lead to an instability. We argue that this distribution behaves as …

Mechanical properties are of central importance to materials sciences, in particular if they
depend on external stimuli. Here we investigate the rheological response of amorphous …

Failure and flow of amorphous materials are central to various phenomena including
earthquakes and landslides. There is accumulating evidence that the yielding transition …

Upon mechanical loading, granular materials yield and undergo plastic deformation. The
nature of plastic deformation is essential for the development of the macroscopic constitutive …
