“…More recent work [16][17][18] has explored the effects of systematic changes in Poisson ratio (e.g., via changes in chemistry or annealing treatment) on ductility [16][17][18][19][20] and toughness, [16] with significant increases in plasticity accompanying higher Poisson ratios, as reviewed elsewhere. [21] Compression tests of many BMGs, conducted at sufficiently low strain rates near the T g , have reported ''homogeneous'' flow, also in agreement with SpaepenÕs free volume theory. However, the cross-sectional area was not monitored in these studies, [4,[22][23][24][25][26] and deformation was assumed to be uniform and thus homogeneous.…”

“…It is known that usually bulk MGs have poor ductility. 25,26 Therefore, an important problem is the enhancement of mechanical properties through understanding the correlation between chemical composition, atomic structure, and macroscopic physical characteristics. In the case of ordinary crystalline alloys, materials with better ductility frequently have higher Poisson's ratio, , or, equally, lower shear ͑G͒ to bulk ͑K͒ modulus ratio.…”

“…Glasses feature remarkable mechanical responses which challenge modeling, among which we note the very high elastic limit [29,43] and the localization of plastic deformation [35,68,74]. Beyond the static mechanical response, let us also mention the anomalous density of low frequency vibrational states giving rise to high heat capacity [24], low heat conductivity [24], low vibrational mean free path for the high frequency vibrational modes [28,61,69].…”
