Phys. Rev. Lett. article on shear-band initiation in metallic glasses
Publications
This Phys. Rev. Lett. article shows via in-situ acoustic emission monitoring that shear-band initiation results from a softening mechanism by local structural dilatation with volume changes of a few percent only. Because these are typical values of excess free volume in the undercooled liquid region near Tg, the onset of plasticity is attributed to a “stress-induced glass transition”.
