In this paper, mechanical properties of nanocomposite materials are studied. Composite material is a material consisting of two or more physically and chemically distinct phase, suitably arranged or distributed. A nanocomposite material usually has characteristics that are not depicted easily. The nanocomposite material used is polytetrafluoroethylene (PTFE) as matrix and expanded graphite as filler material. Digimat software is used to find out mechanical properties of the nanocomposite materials. Digimat-MF and Digimat-FE are complimentary tools used for nanocomposites modelling. Digimat-FE, based on direct nonlinear Finite Element Analysis (FEA), offers accurate predictions at the macroscopic and local microscopic scales. The mechanical behaviour of the composites such as elastic plastic and damage properties are calculated numerically with 3D representative volume element (RVE) models. In PTFE material the varying composition i.e. 0.15%, 0.25%, 0.35%, 0.45%, 0.5% etc. of expanded graphite is mixed. Mechanical properties such as Youngs modulus, Shear modulus, poisons ratio, density etc. are find by using digimat software.
