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 …

Mechanical yield in amorphous solids: A first-order phase transition
Amorphous solids yield at a critical value of the strain (in strain-controlled experiments); for
larger strains, the average stress can no longer increase—the system displays an …
