Elastoplastic description of sudden failure in athermal amorphous materials during quasistatic loading

M Popović, TWJ de Geus, M Wyart - Physical Review E, 2018 - APS
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 …

A stability-reversibility map unifies elasticity, plasticity, yielding, and jamming in hard sphere glasses

Y Jin, P Urbani, F Zamponi, H Yoshino - Science advances, 2018 - science.org
