Transforming mesoscale granular plasticity through particle shape
When an amorphous material is strained beyond the point of yielding, it enters a state of
continual reconfiguration via dissipative, avalanchelike slip events that relieve built-up local …

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 …
