Effect of different tensile loading modes on deformation behavior of nanocrystalline copper: Atomistic simulations

The present analysis focus on the mechanism of deformation in different tensile deformation modes. Uniaxial, plane strain and equi-biaxial tensile deformation modes play a significant role in determining the yield stress of the material. Yielding of the material begins with nucleation of 1/6<112> Shockley partial dislocation and subsequent deformation cause an increase in dislocation line length in the material. Consequently, strain hardening is...
