MOLECULAR DYNAMICS SIMULATION OF NANOINDENTATION ON CUNANO PARTICLE AND EXTRAPOLATING TS MECHANICALBEHAVTOR

Molecular Dynamics (MD) Simulations is widely used nowadays in prediction of mechanical behavior of nano materials. In this study we simulated a Fcc nano particle of Cu under a rigid spherical indenter using EAM (embedded atom method) and studied the effect of thickness on its hardness and on dislocations nucleation. As thickness decreased, more force was needed to make plastic deformation inside the bulk.
