A linear elastic continuum model for dislocation loops in tungsten matches atomistic far-field displacements and decay rates, converging as simulation size increases.
If one thinks of dislocation loops as point particles interacting with one another in a large system, the average interaction distance can be found as⟨r⟩ ∼ρ −1/3 for a densityρ
