Describe multilayer buckling
Webbuckling profile, which evolves into the chevron shape on further strain beyond the instability. The buckling is associated with a sharp turnover in the stress–strain curve. We also set our work in the context of treatments of similar buckling instabilties found in the fields of structural geology and liquid crystals. 1. Introduction WebA schematic illustration of multilayer graphene lamination is shown in Fig. 3, where different colors represent different boundary conditions.In the MD simulation of MLG, we adopted a large-scale atomic/molecular massive parallel simulator (LAMMPS) [34].Periodic boundary conditions were imposed in the three directions of the initial model: group a was defined …
