| Abstract Scope |
It is now possible to routinely perform atomistic simulations at the microsecond timescale. In the present work, we exploit this for a model binary Lennard-Jones glass to study structural relaxation at a timescale spanning several tens of microseconds, and the collective plastic shear activity under simple shear spanning six orders of magnitude strain rate. It is found that at these longer time-scales, significant thermally activated mobility and relaxation occurs, that is intimately linked to the ongoing structural relaxation, producing a rich spectrum of atomic-scale activity in terms of spatial and temporal correlation, both in the elastic and plastic regimes of deformation. |
