Fig. 1. Visualisation of the Young modulus (left) and the Poisson ratio (right) of single-crystal copper.

The visualisation of Young’s modulus as well as Poisson’s ratio of single crystal copper is shown in Fig. 1. Then, the material with the same type of the symmetry has been analysed. The monocrystalline aluminum belonging to the same class of the cubic singony is studied. The elastic tensor components of the monocrystalline aluminum are evaluated via molecular dynamics simulations (in GPa): 107.25 81.44 81.44 0 0 0 81.44 107.25 81.44 0 0 0 81.44 81.84 107.25 0 0 0 0 0 0 46.16 0 0 0 0 0 0 46.16 0 0 0 0 0 0 46.16                     (4) The elastic tensor and the Poisson ratio for single crystal aluminum are shown in Fig. 2.
