摘要

Abstract

Shear localization is an important failure mechanism in crystalline solid materials. However

while nanograins (NGs) are universally observed in shear bands

their connection with the formation of the bands is not clear yet. Based on molecular dynamics (MD) simulations

we propose that the shear localization evolves as a percolative process of deformation zones between NGs. The presence of NGs is a necessary condition to relieve some of the elastic energy by dislocation emission and absorption. Moreover

the density and spatial arrangement of those grains are of prime importance to accelerate or delay the formation of a strong localization path.
