The encapsulation of nanowires (NWs) into single-walled carbon nanotubes (SWCNTs) is of great signi cance due to the speci c mechanical, electrical and magnetic properties of con ned NWs as well as application of lled CNTs in nanoelectromechanical systems (NEMS). The tensile behavior of NWs encapsulated-SWCNTs (NWs@SWCNTs) is investigated herein using molecular dynamics (MD) simulations. The results illustrated that Young's moduli of NWs@SWCNTs decrease as the length of nanotube increases. Moreover, pure SWCNTs show higher Young's moduli as compared to NWs@SWCNTs. It is also found that NWs@SWCNTs possess higher ultimate forces than those of pure SWCNTs. In addition, at a given length, the ultimate forces of pure SWCNTs and NWs@SWCNTs increase by increasing the radii of nanotubes.
