Abstract

To examine the effect of aspect ratio, atomistic simulations are performed on the tensile failure of Cu₅₀Zr₅₀ metallic glasses (MGs) with aspect ratios from 2:1 to 12:1. All samples fail via a single shear band (SB), and the Young's modulus and the tensile strength are independent of the aspect ratio. For long MGs, however, an abrupt unstable shear banding failure is observed, while a combined abrupt unstable shear banding and slow stable SB sliding is observed for short MGs.
