Abstract

The microstructural design and modeling of composite materials plays a significant role in both computational and manufacturing innovations. The computational modeling provides the opportunity to rapidly access the influence of the constituents in the metal matrix composites (MMC) on the overall performance of the composite at a minimum cost. However, the continuum descriptions of mechanical behaviors of MMC via the atomistic-informed multiscale method are not fully available. A multiscale analysis of nickel coated continuous carbon fiber reinforced aluminum metal matrix composite is presented herein with different microstructural geometric models and volume fraction of micro constituents. The methodology involved different length scales ranging from nano to macro scales. In this hierarchical multi-scale modeling technique, the outputs of each lower scale are fed into the next higher scale as input data. Molecular Dynamics modeling was performed at the nano scales and polycrystalline materials model was done at meso scale. High-fidelity Generalized Method of Cells (GMC) micromechanical model was utilized at the macro length scale. The results are in agreement with the experimental data in the literature and also provide a better understanding of the link between the material variables and the composite performance.
