| Abstract Scope |
Dislocation slip in ice occurs at low stresses, a behavior linked to proton disorder in its hydrogen-bonded network. However, the atomic-scale mechanisms behind this remain unclear. In this computational study, we employ both all-atom and coarse-grained molecular dynamics simulations to investigate the mechanisms governing dislocation mobility in ice. Our dual-approach allows for a detailed comparative analysis of dislocation glide and the complex interplay between dislocation glide and Bjerrum defect formation. By bridging these atomic-scale processes with macroscopic mechanical properties, these findings can have significant implications for glaciology and materials engineering in cold environments. |
