Studying the effect of strain rate on tensile properties of nanocrystalline Cu50Ni50 alloy using molecular dynamics simulation method

Abstract

In this paper, the effect of different strain rates on the tensile properties of nanocrystalline Cu₅₀Ni₅₀ alloy was investigated using the molecular dynamics simulation method, one of the simulation methods widely used in the field of nanomaterials today. The Voronoi method was applied to establish the nanocrystalline structure, and ATOMSK software was used to create the tensile test specimens of the polycrystalline Cu50Ni50 alloy. The stress-strain relationship,
phase transformations, lattice dislocations, shear strain and von Mises stress distributions were evaluated...
