Mechanical behavior of Al-CNT nanocomposite

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 betteruse of them. In this study, first, mechanical molecular dynamics method is used to investigate mechanicalproperties of aluminum/carbon nanotubes (Al-CNT) nanocomposite. Then, the effect of ambient pressureand chirality of nanotubes on the tensile fracture stress, and yield stress of nanocomposite have beeninvestigated. However, in order to simultaneously investigate these two parameters on the properties ofnanocomposite and to find an optimal point for the tensile fracture stress, and yield stress, the moleculardynamics simulation method was used. The results showed that if the ambient pressure increases, the tensilefracture stress and yield stress will increase. Furthermore, the higher the chirality is, the higher the tensilefracture stress and yield stress are.
