In this study, elastic properties of stanene under biaxial tensions along armhair and zigzag directions are investigated by
molecular mechanic (MM) calculations. Modified embedded-atom method (MEAM) which is a kind of many-body
interatomic potential is implemented to consider pairwise interactions between atoms. surface of strain energy density is
attained through fitting a fourth-order polynomial function to quantities of strain energy density corresponding to
representative volume elements (RVE’s) then atomic linear elastic parameters are obtained through computing second-order
derivative of surfaces and curves of strain energy density with respect to strain.In addition, a novel multiscale hierarchical
molecular mechanic (MM) – finite element (FE) coupling method is proposed to illustrate the accuarcy of elastic properties
in continuum level
