heal.abstract
The thesis investigates a composite material's response to deformation through simulation of nanoindentation using finite element analysis. The geometry of a metal matrix composite (MMC), comprising of an aluminum matrix reinforced with silicon carbide (SiC) nanoparticles was modeled with the use of a mathematical algorithm generated with the help of a parametric CAD software. The algorithm used the Voronoi diagram to achieve random distribution of particles inside the matrix and random particle size. The results of the simulation showed an upturn in the composite's mechanical properties related with the volume percentage of the reinforcement. Increase in particle concentration lead to increase in the material's ability to resist deformation while converting the aluminum matrix from isotropic to anisotropic. 2
