Detecting low-energy quasilocalized excitations in computer glasses
David Richard, Geert Kapteijns, Edan Lerner
Soft, quasilocalized excitations (QLEs) are known to generically emerge in a broad class of disordered solids, and to govern many facets of the physics of glasses, from wave attenu…
Bridging necking and shear-banding mediated tensile failure in glasses
David Richard, Ethen Lund, Jan Schroers +1
The transition between necking-mediated tensile failure of glasses, at elevated temperatures and/or low strain-rates, and shear-banding-mediated tensile failure, at low temperature…
Mechanical excitation and marginal triggering during avalanches in sheared amorphous solids
David Richard, Ahmed Elgailani, Damien Vandembroucq +2
We study plastic strain during individual avalanches in overdamped particle-scale molecular dynamics (MD) and meso-scale elasto-plastic models (EPM) for amorphous solids sheared in…
Bond-space operator disentangles quasi-localized and phononic modes in structural glasses
Julia A Giannini, David Richard, M. Lisa Manning +1
The origin of several emergent mechanical and dynamical properties of structural glasses is often attributed to populations of localized structural instabilities, coined quasilocal…
Brittle to ductile transitions in glasses: Roles of soft defects and loading geometry
David Richard, Edan Lerner, Eran Bouchbinder
Understanding the fracture toughness of glasses is of prime importance for science and technology. We study it here using extensive atomistic simulations in which the interaction p…
Does mesoscopic elasticity control viscous slowing down in glassforming liquids?
Geert Kapteijns, David Richard, Eran Bouchbinder +3
The dramatic slowing down of relaxation dynamics of liquids approaching the glass transition remains a highly debated problem, where the crux of the puzzle resides in the elusive i…
