The tensile stress behaviour of Aluminium Metal Matrix Composites (AMCs) reinforced with SiO 2 was evaluated using Molecular Dynamics (MD). A cubic model was used for the simulation, while the Modified Embedded Atom Method (MEAM) was implemented to describe the atomic interactions for the MD simulation. From the MD simulation the presence of the SiO 2 was found to substantially disrupt the FCC crystallography of the Al and reduce the ductility of the Al while substantially increasing the yield strength of the composite. A Maximum Elastic modulus of 43.3GPa was obtained at a temperature of 350K and 10wt% SiO2.
