Molecular dynamic simulation of uniaxial tension deformation applied to α-Fe nanowire

In this study, using the Molecular Dynamics (MD) simulation method, effects of tensie stress applied to Fe nano wire along direction [100] for different temperatures and strain rates were tried be determined. The stress-strain curve, Young’ s modulus, yield plastic deformation model system under tensile investigated. Embedded Atom Method (EAM), which includes many body interactions, was used determine interactions between atoms. It determined that temperature rate had an effect on mechanical behaviour α-Fe nanowire. found modulus is independent at low temperatures, but decreases with increasing temperature. also flow decreased decreasing rate. motion dislocations twinning corresponding resulting reorientation regional crystal structures attempted by method Common Neighbour Analysis (CNA).
