Abstract
In this study, the mechanical properties of an aluminum 6061-based nanocomposite reinforced with Silicon Carbide (SiC) nanoparticles were investigated. The factors examined included the size, geometry, and volume fraction of the nanoparticles. Using the Random Sequential Adsorption (RSA) algorithm, a Representative Volume Element (RVE) of the nanocomposite with randomly distributed spherical and elliptical particles was simulated. The results showed that increasing the volume fraction of nanoparticles leads to improved mechanical properties, including elastic modulus, shear modulus, yield strength, and ultimate tensile strength. In samples reinforced with spherical nanoparticles at a 10% volume fraction, mechanical properties decreased with increasing particle size. Furthermore, the mechanical properties of nanocomposites reinforced with elliptical particles were lower compared to those reinforced with spherical particles.
