Elastoplastic description of sudden failure in athermal amorphous materials during quasistatic loading
The response of amorphous materials to an applied strain can be continuous or instead
discontinuous if the initial configuration is very stable. We study theoretically how such a …

Elastic avalanches reveal marginal behavior in amorphous solids
Mechanical deformation of amorphous solids can be described as consisting of an elastic
part in which the stress increases linearly with strain, up to a yield point at which the solid …

Brittle yielding of amorphous solids at finite shear rates
Amorphous solids display a ductile to brittle transition as the kinetic stability of the quiescent
glass is increased, which leads to a material failure controlled by the sudden emergence of …

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 …
