Metals are hugely applied in manufacturing such as aerospace and automobile. The coherent role to understand the Aluminum material has extremely manifested in structural analysis at the atomic scale. This investigation paper provides a brief summary focused on the influence of the interatomic potentials categories in applied deformation. Based on atomistic simulations, the Embedded Atom Method (EAM) and the Modified Embedded Atom Method (MEAM) potentials are used to perform accurately the differences and similarities. The internal vectors involved in atomic configurations were depicted by features matrix and the mechanical properties were calculated using the linear fitting as an approach method. The implementation of (MD) simulations allows clarifying the occurred divergence using specific parameters in each compression and tensile deformations. The simulations results agree with experimental observations in FCC crystalline Al. The application of MEAM potential showed the raised compactness by calculations the interatomic distance, at initial state and after each numerical process of deformation in the first detection of atomic neighbors. The material act differently, and depict a disparity in particular regions. More attention is in the following paper.
