In this case, the nanofiber of iron atoms is a kind of reinforcing material. Nanofiber smooths the main stresses and strains. The rearrangement of the coordinate positions of the atoms of the nanocomposite proceeds gradually. Thus, this nanocomposite is more resistant to damage during shear deformation than a nanocomposite with a nanoparticle. x y z a) с) b) Figure 8: Shear deformation of an aluminum nanocomposite with an iron nanocylinder for a simulation time of 5 psec (deformation 0.035) a; 45 psec (deformation 0.315) b; 100 psec (deformation 0.700) c. C ONCLUSIONS he paper proposes approaches to observe the processes of deformation and fracture of nanocomposites. Simulation of the processes of deformation and failure of nanocomposites was carried out by the method of molecular dynamics using the potential of the modified embedded atom method. The used multiparticle interatomic potential allows to study the behavior of composite materials under mechanical loading in detail at the nanoscale level, analyze the processes of deformation and fracture, and study the nature of the origin and development of defects and dislocations in them. The results of the research can be used to study the processes of deformation of nanocomposite materials with promising functional properties. The tasks of further research include studies of nanocomposites with a more complex structure and complex deformation programs.
