Abstract

Simulations of load-displacement relations for the nanoindentation of thin metal films on ceramic substrates by both ideal and blunt Berkovich indenters were performed using the large strain elastoplastic feature of the ABAQUS finite element code. The functional equations have been developed to predict the relations among the mechanical properties of film and substrate, the relative blunting ratio of the indenter, and the nanoindentation loading curve. A new method for obtaining the yield strength and hardening index of metal film from nanoindentation loading curve is then proposed.
