Shear transformations, as fundamental rearrangement events operating in local regions, hold the key of plastic flow of amorphous solids. Despite their importance, the dynamic features of shear transformations are far from clear, which is the focus of the present study. Here, we use a colloidal glass under shear as the prototype to directly observe the shear-transformation events in real space. By tracing the colloidal-particle rearrangements, we quantitatively determine two basic properties of… Expand

This work carries out case studies using atomistic simulations of a three-dimensional Cu50Zr50 model glass under athermal, quasistatic shear, and reveals that low-frequency modes get highly entangled with each other, from which the critical mode emerges spontaneously to predict a shear transformation event.

Key role of excess atomic volume in structural rearrangements at the front of moving partial dislocations in copper nanocrystals
The simulation shows that the leading and trailing partial dislocations surrounding a stacking fault move via local fcc→hcp and hcp→fcc transformations and that a fcc–hcp transition zone exists in which the atomic volume is larger than that in the perfect close-packed structure. Expand

Local shear transformations in deformed and quiescent hard-sphere colloidal glasses.
It is found that shear transformation zones exist and are active in both sheared and quiescent colloidal glasses, revealed by a distinctive fourfold signature in spatial autocorrelations of the local shear strain. Expand

Based on the shear-transformation-zone (STZ) theory, we propose a constitutive model for describing homogeneous elastoplastic deformation of amorphous solids where the interaction of shearExpand
Plastic deformation of metallic glasses: Size of shear transformation zones from molecular dynamics simulations
Plastic deformation in metallic glasses well below their glass transition temperatures Tg occurs spatially heterogeneously within highly localized regions, termed shear transformation zones (STZs).Expand
Elastic signature of flow events in supercooled liquids under shear.
It is shown that, in the Newtonian regime, thermal activation triggers shear transformations, i.e., local irreversible shear events that produce Eshelby (long-ranged, anisotropic) deformation fields as previously seen in low-T glasses. Expand

Long-range strain correlations in sheared colloidal glasses.
By imposing an external stress, the applied shear induces a transition from homogeneous to inhomogeneous flow at a critical shear rate, and the role of strain correlations in this transition is investigated. Expand

A rheology model is proposed to quantitatively explain viscosity by determining the activation energy barrier and plastic yield strain of individual shear transformation zones as a function of size and external stress loading in classical molecular dynamics computer simulations on the model glass, CuTi.
