Abstract: Atomistic simulations of nanoindentations with spherical and Berkovich indenters were carried out to study the effects of size on nanohardness. For spherical indenters with the radii ranging from 10 Å to 50 Å, it was found that nanohardness was inversely proportional to the indenter radius. For Berkovich indenters, it was found that nanohardness roughly followed a trend that was inversely proportional to the indentation depth. It was concluded that the indentation size effect at the atomistic scale might follow a trend similar to that observed at the micron and sub-micron scales.
