Experimental evidence shows that some Nano-composites have particular importance in armor vehicles structures. Simulation and finding the properties of these Nano-composites analytically or numerically is an essential work, due to the cost of Nano reinforcements and their production complexity with current methods. This paper employs analytical- experimental constitutive equations of energy absorption in composite Nano-Armors and various approaches for using in Nano-armors simulation. In these studies, the constants values required for numerical simulation are obtained by the experimental tests. So, considering these constants can be extracted from molecular dynamics simulations, the use of finite element method combined with molecular dynamics simulations its essentials in these simulations.
