Abstract

Metallic nanowires have the potential to be or enhance the basic building blocks of nanomaterials. They are a key subject of research in the field of nanomaterials and nanocomposites. The subject of this research concerns the mechanical behavior of several ratios of Copper Nickel core-shell nanowires, a cylindrical composition of two nanomaterials. The mechanical behavior is determined using Molecular Dynamics simulated tensile tests on the nanowires. The tested nanowires have a length of 46 [nm], the diameter ranges from 7 to 25 [nm]. All nanowires were tensile tested for three strain velocities. The equilibration, tensile strength and deformation behavior were studied. The results show that single element nanowires have a higher ultimate tensile strength than core-shell nanowires. Tensile properties of the single element crystal nanowires are several times higher than the copper and nickel bulk materials. These tensile properties show that single element nanowires can be used to reinforce other nano- or macrostructures. A future application of these nanowires is therefore to enhance the mechanical behavior of other (nano)materials. The importance of the suggested research stems from the lack of available knowledge for copper nickel core-shell nanowires specifically and their comparison to pure element nanowires.
