摘要：Flow unit (FU), as the fundamental carrier of plasticity, is central to the mechanical behaviors of amorphous solids. Despite its importance, however, the structural origin of itself has remained elusive. This has been due in part to the limitations of existing experimental evidence for FUs. Here, we used a simple colloidal glass as model to monitor the plastic behavior of amorphous solid on particle level. We directly visualized the FUs in real space.

Flow unit (FU), as the fundamental carrier of plasticity, is central to the mechanical behaviors of amorphous solids. Despite its importance, however, the structural origin of itself has remained elusive. This has been due in part to the limitations of existing experimental evidence for FUs. Here, we used a simple colloidal glass as model to monitor the plastic behavior of amorphous solid on particle level. We directly visualized the FUs in real space. It is observed that the FUs initiate preferentially from liquid-like regions. More specifically, liquid like particles possessing high dilatancy ability prefer to participate in the operation of FUs.
