Fig. 8: A model for simultaneous and progressive propagation of SBs.
From: How to catch a shear band and explain plasticity of metallic glasses with continuum mechanics
Depicted is a hypothetical MG specimen with marked points “A” and “B” as well as the surface traces between these points (a). When the load is applied, an SB is generated at A and extends towards B. If the SB arrest condition is violated across the whole distance AB, then the SB will propagate at once, and all surface traces will exhibit the same shear displacement, which can be interpreted as simultaneous slip (b). If the SB experiences several arrest and re-activation events during propagation from A to B, then the surface traces will exhibit a gradient in shear displacement: from maximal close to A to minimal close to B (c).
