Query: Mechanical Properties of Phagraphene Membranes: A Fully Atomistic
  Molecular Dynamics Investigation   Recently, a new 2D carbon allotrope structure, named phagraphene (PG), was
proposed. PG has a densely array of penta-hexa-hepta-graphene carbon rings. PG
was shown to present low and anisotropic thermal conductivity and it is
believed that this anisotropy should be also reflected in its mechanical
properties. Although PG mechanical properties have been investigated, a
detailed and comprehensive study is still lacking. In the present work we have
carried out fully atomistic reactive molecular dynamics simulations using the
ReaxFF force field, to investigate the mechanical properties and fracture
patterns of PG membranes. The Young's modulus values of the PG membranes were
estimated from the stress-strain curves. Our results show that these curves
present three distinct regimes: one regime where ripples dominate the structure
and mechanical properties of the PG membranes; an elastic regime where the
membranes exhibit fully planar configurations; and finally a plastic regime
where permanent deformations happened to the PG membrane up to the mechanical
failure or fracture.
