Molecular Dynamics Simulations of the Shear Bands Formation of Single Crystal Bulk Copper during the High Strain Rate Compressive Process

Abstract:

In this work, the high strain rate compressive process of single crystal bulk copper was studied by molecular dynamics (MD) simulations. The simulated result indicated that the localized deformation caused the formation of shear bands (SBs). It was found that the formation of shear bands in single crystal was owing to a plenty of the plastic deformations that caused by dislocations slippage or twinning concentrated in a narrow region [1], and the temperature at the shear bands region was rising more quickly than the others.
