Locality of forces in case of atom-centered three- or higher-body order potential terms. The displacement of atom A affects the local atomic energy of atom B, which in turn affects the force on atom C. Both atoms A and C are just within the cutoff radius of atom B, and thus the locality of the forces in the model is twice the cutoff radius.
