Tetrahedral species and their plastic properties. a Schematic of spatial relationship of the three types of tetrahedra. b Correlation between non-affine mobility \(\mu\) and shape parameter δ for three types of tetrahedra. c Normalized square non-affine displacements of particles vs. distance r from the unstable and stable cores. The unstable cores are geometrical centers of unstable tetrahedra. The stable cores are geometrical centers of stable tetrahedra. d Fraction of three types of tetrahedra as a function of the shape parameter δ
