TL;DR: The aged-rejuvenation-glue-liquid (ARGL) shear band model has been proposed for metallic glasses based on small-scale molecular dynamics simulations up to 20,000 atoms and thermomechanical analysis as mentioned in this paper.

TL;DR: In this article, the embryonic shear band propagation in bulk metallic glasses is studied. But the critical condition for propagation is not its nucleation, but the far-field shear stress s1 � Eey/2 must exceed the quasi-steady-state glue traction sglue of shear-alienated glass until the glass transition temperature is approached internally due to frictional heating, at which point ESB matures as a runaway shear crack.

TL;DR: In this article, shear deformations of Cu 57 Zr 43 bulk metallic glass (BMG) model systems are performed using molecular dynamics simulation, and the results suggest that both the hydrostatic stress and the stress normal to the shear plane should affect the response (modified Mohr-Coulomb yield criterion).

TL;DR: In this article, critical conditions have been determined for intrinsic transformation of a vacancy Frank loop into a stacking fault tetrahedron in a face centered cubic metal by the molecular dynamics method.

TL;DR: In this paper, the authors studied the behavior of dislocations near a crack tip in an fcc lattice and revealed three-dimensional features of dislocation nucleation and subsequent entanglement.
