Abstract Scope |
Molecular dynamics simulations provide the opportunity to 'see'
the atomic-scale deformation mechanisms of dislocation - obstacle interactions, albeit usually at accelerated strain rates. By coupling atomic-scale modeling with in-situ straining studies in the transmission electron microscope, significant insight has been obtained that validates key mechanisms predicted in the MD studies. This presentation will highlight studies of dislocation – obstacle interactions performed collaboratively with the Robertson group that led to new insights into the defect-free dislocation channel formation in deformed, irradiated copper and that highlight how fundamental dislocation reaction analysis provided a foundation for the collaborative analysis. |
