Deformation mechanism, nano void nucleation and failure of nano crystalline aluminum are investigated for uniaxial, plane strain and equi biaxial loading conditions using atomistic simulation technique. Nano deformation twin formation is noticed for all three loading conditions. Grain boundary triple point is the site of nano void nucleation and the fracture mode is intergranular type. Early nano void nucleation and failure are observed in plane strain loading condition in comparison with uniaxial and equi biaxial loading conditions. (C) 2017 Elsevier Ltd. All rights reserved.
