The objective of this study is to understand the behavior of a metal matrix composite (MMC) through computational simulations. To achieve this goal, a Python code was developed to perform simulation routines in Abaqus® software, with the purpose of increasing the number of simulations performed and obtaining a better understanding of the behavior of the MMC. In the analysis process, several parameters were evaluated, including mesh refinement, type of element, reinforcement angle, and volume fraction. These variables were adjusted to observe their effects on the properties of the composite material, and the result is described in this work. Additionally, two other codes, totaling 3 were created to generate a simulation of an expanded model, with the first one having reinforcements aligned in the direction of force and the second one considering a random angle. This model was then used to calculate the homogenized elastic modulus, which was later compared to theoretical values obtained through equations present in specialized literature. The study aims, therefore, to contribute to the advancement of knowledge about metal matrix composites by analyzing their behavior and properties. With this, the author hopes to better understand these materials, helping to further drive technological developments in various areas, expanding the potential application of MMC, opening doors for new research, and benefiting the scientific community.
