Objective molecular dynamics simulations combined with an effective-tensional-strain concept provide a new theory for describing the electromechanical properties of nonideal twisted structures of graphene nanoribbons. It is shown that from the effective-strain perspective, the twist-induced bandgap modulations in graphene nanoribbons appear strikingly similar to those exhibited by the seamless carbon nanotubes.
