• Resumen

  • Low velocity impact behavior of multi-walled carbon nanotube (MWCNT)-aluminum (Al) nanocomposite plates are investigated. The rule of mixture is employed to obtain the material properties of the nanocomposites. The microstructural features, including amount, aspect ratio, alignment, waviness, and agglomeration of the MWCNTs are considered.

    The finite element method is used to investigate the plate dynamic behavior. Addition of the MWCNTs increases the contact force and decreases both the plate center deflection and impact duration. A higher volume fraction, higher aspect ratio, straight shape, and a uniform dispersion of MWCNTs can cause a lesser center deflection of the nanocomposite plate
