Fig. 4: Yield shear stress τy as a function of indenter radius R.
From: Atomic-scale homogeneous plastic flow beyond near-theoretical yield stress in a metallic glass
Plot of τy in fractions of the shear modulus G, with G/40 reflecting the material’s bulk value. The green hexagons mark the results obtained on Pt57.5Cu14.7Ni5.3P22.5 in this work while all other data points are taken from Fig. 2 in ref. 11. Note that the fit given in that reference, reflected by the dashed magenta line, coincides favorably with the dashed purple line we find using Pt-BMG data only.
