| Abstract: | The mechanical stability and theoretical strength of FCC crystal Cu under 110] uniaxial loading were investigated by combining MAEAM with Wang et al modified Born stability criteria. The results revealed that, the calculated elastic moduli of FCC phase are in good agreement with the experimental values. The stable region ranges from- 263.4 - 4.03 GPa in the theoretical strength or 0.796 -1. 066 in the stretch 1 correspondingly. |
