Figure 2

Residual stresses for the bulk metallic glass (BMG) sample (Vit-105) after LSP to a power density of 8.64 GW/cm compared to model simulations, (a) assuming that there is no strain-rate effect and (b) including strain-rate softening at high strain rates. The compressive plateau is taken to be the residual-stress state introduced by the surface preparation prior to micro-slotting. The colors of simulated tracks correspond to those in Figure 1a.
