Shear deformations of CuZr bulk metallic glass (BMG) model systems are performed using molecular dynamics simulation. The results suggest that both the hydrostatic stress and the stress normal to the shear plane should affect the shear response. We see shear localization and shear band nucleation in both a small system of 2,000 atoms, and large systems of 524,288 atoms, and analyze local atomic structure evolution.
