| چکیده مقاله |
| Nowadays, various methods are being formed on new composites and nanocomposite compounds. Investigating the properties of nanocomposites and finding their optimal properties pave the way for a better use of them. In this study, first, mechanical molecular dynamics method is used to investigate mechanical properties of aluminum/carbon nanotubes (Al-CNT) nanocomposite. Then, the effect of temperature and strain rate on the tensile fracture stress, and yield stress of nanocomposite have been investigated. However, in order to simultaneously investigate these two parameters on the properties of nanocomposite and to find an optimal point for the tensile fracture stress, and yield stress, the molecular dynamics simulation method was used. The results showed that if the temperature increases, the tensile fracture stress and yield stress will decrease. Furthermore, the higher the strain rate is, the lower the tensile fracture stress and yield stress are. Both temperature and strain rate showed influential effect on the mechanical properties of Al-CNT nanocomposite. |
