Scaling description of the yielding transition in soft amorphous solids at zero temperature
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 …

[HTML][HTML] Stress localization, stiffening, and yielding in a model colloidal gel
J Colombo, E Del Gado - Journal of rheology, 2014 - pubs.aip.org
We use numerical simulations and an athermal quasistatic shear protocol to investigate the
yielding of a model colloidal gel. Under increasing deformation, the elastic regime is …

Encoding of memory in sheared amorphous solids
We show that memory can be encoded in a model amorphous solid subjected to athermal
oscillatory shear deformations, and in an analogous spin model with disordered interactions …

Avalanches in strained amorphous solids: Does inertia destroy critical behavior?
Simulations are used to determine the effect of inertia on athermal shear of amorphous two-
dimensional solids. In the quasistatic limit, shear occurs through a series of rapid …

A stability-reversibility map unifies elasticity, plasticity, yielding, and jamming in hard sphere glasses
Amorphous solids, such as glasses, have complex responses to deformations, with
substantial consequences in material design and applications. In this respect, two …
