Abstract：The mechanical study of silver nanowires with different orientations and sizes of silver nanowires was carried out by using molecular dynamics software lammps. The results of the experiments were treated by EXCEL, VMD and MATLAB. The strain energy, torsion curve, and the young's modulus was obtained. A variety of methods for calculating Young's modulus were explored. At last, the function of the three time type is simulated, and strain energy is used to calculate Young's modulus. On the same orientation of crystal, the mechanical properties of different sizes of silver nanowires are compared: different sizes of silver nanowires show different Young's modulus, but the increases or decreases of Young's modulus with size is relevant with orientation of crystal , and different crystal of Young's modulus showed hardening or softening. For the same size , mechanical properties of different orientation of crystal of the silver nanowires are compared : the young's modulus of different crystal silver nano nanowires are different, even if axial orientation of crystal are the same one and the other direction is different, the young's modulus is a greater difference. The comparison of Young's modulus with different forces is carried out.. In conclusion, the young's modulus is not only affected by the size, but also influenced by the direction of the crystal direction.. At last, the limitation of the paper and the prospect of the future are discussed.
