James [6]. The key ingredient of objectivemolecular dynamics is that the action of the group on the fundamental
domain is not restricted to be the group of translations. In this respect, objectivemolecular dynamics generalizes
periodic molecular dynamics to cases where the structure is not even periodic. This framework is successfully
applied to treat, e.g., rod problems [18], graphene nanoribbons [5], bulk materials and nanostructures [4] as
well as dislocations onset [34].
