Abstract

The technique of nanoindentation is now widely used to determine the hardness and Young's modulus of thin films. Unless complex analyses procedures are used it is important in an experiment to avoid penetrating into the film with the identer tip to a point where the properties of the substrate material introduce a significant error. The usual role-of-thumb employed in this respect is that the maximum penetration should be more than 10% of the film thickness. In order to test this rather arbitrary rule we have performed a series of 2-D finite-element simulations of the nanoindentation process for aluminium oxide films on a nickel substrate.

Simulations were made using the ABAQUS software for three different film thicknesses and for both a perfect sharp and a rounded tip. .
