I. Introduction
Metallic nanostructures, due to their efficient elec-trical, physical and chemical properties, have wide range of applications as components for various nanoe-lectronic devices [1]. Nowadays, various methods of synthesis [1]–[6] can be used to obtain metallic nanopar-ticles, nanotubes and nanowires of different shapes, structures and chemical compounds. Beside the exper-imental research, metallic nanostructures intensively studied by computational methods [6]–[8]. In this work we present the results of the computational study of the mechanical properties of Au (core)-Ag (shell) nanowires with core-shell structure by molecular dynamic simulations.
