Snapshots of atomic displacement of the studied CMGN structures at the elastic limit and the yield point, respectively. The rotational angles are configured by atom displacement.


Stress and instantaneous Poisson’s ratio of S3 as a function of strain in thexdirection. Stage I: elastic stage; Stage II: elastoplastic stage; Stage III: fracture stage.


Snapshots of S3 under tensile strains of (a) 0%, (b) 3%, (c) 8%, and (d) 18%, colored by atomic local shear strain. The right column shows the larger image of the unit cell, obvious deformation and shear transformation zones (STZs) are observed in (c) and (d).
