Özet
This study is a comprehensive analysis to demonstrate the deformation and failure mechanism of hexagonal Zr nanowires in [0 0 0 1] orientation. Molecular dynamics simulations in conjunction with embedded atom potentials are utilized to determine the effect of the temperature, diameter and strain rate on mechanical properties of nanowire. We have observed two basic scheme that these parameters have different impacts on elastic and plastic deformations of Zr nanowires. The elastic response of nanowire increases by high strain rate, low temperature and small diameter. Although Young's Modulus can be characterized by strain rate, the temperature and the diameter are more effective key variables in engineering of strength mechanism. On the other hand, high strain rate, low temperature and large diameter decrease the failure of Zr nanowires.
