Experimental evidence that shear bands in metallic glasses nucleate like cracks
Scientific Reports, 2022 Highly time-resolved mechanical measurements, modeling, and simulations show that large shear bands in bulk metallic glasses nucleate in a manner similar to cracks. When small slips reach a nucleation size, the dynamics changes and the shear band rapidly

Deformation-driven catalysis of nanocrystallization in amorphous Al alloys
Beilstein Journal of Nanotechnology, 2016 Nanocrystals develop in amorphous alloys usually during annealing treatments with growth- or nucleation-controlled mechanisms. An alternative processing route is intense deformation and nanocrystals have been shown to develop in shear bands during the ...

Crossing of shears bands in 196Pb
Zeitschrift für Physik A Hadrons and Nuclei, 1996 High-spin states in 196Pb have been populated using the reaction 170Er(30Si,4n). The previously observed shears bands in this nucleus have been extended and some of their transitions have been reordered. They now form regular bands with band crossings. One of the bands splits into two pathways at high spin.

The genesis of adiabatic shear bands
Scientific Reports, 2016 AbstractAdiabatic shear banding (ASB) is a unique dynamic failure mechanism that results in an unpredicted catastrophic failure due to a concentrated shear deformation mode. It is universally considered as a material or structural instability and as such, ASB is hardly controllable or predictable to some extent.

Journal of Materials Research and TechnologyStrain path changes of the accumulative roll bonded 90Cu–10Zn brass and its influence on the shear band structure is the aim of the present study. The effect of post-annealing was also studied in terms of shear bands and texture development.

The dynamics of a shear band [PDF]
Journal of the Mechanics and Physics of Solids, 2018 A shear band of finite length, formed inside a ductile material at a certain stage of a con- tinued homogeneous strain, provides a dynamic perturbation to an incident wave field, which strongly influences the dynamics of the material and affects its path to failure. The investigation of this perturbation is presented for a ductile metal, with reference

Shear-banding instability in arbitrarily inelastic granular shear flows [PDF]
Physical Review E, 2019 One prototypical instability in granular flows is the shear-banding instability, in which a uniform granular shear flow breaks into alternating bands of dense and dilute clusters of particles having low and high shear (shear stress or shear rate), respectively.
