Indentation Size Effect in the Nanohardness of Soda-Lime Glass


Article Preview

The nanoindentation load-displacement curves of soda-lime glass were analyzed with the widely adopted Oliver-Pharr method. The resultant nanohardness exhibits a significant indentation size effect (ISE). An empirical relationship between the peak load and the contact depth, which was established to analyze the ISE in microhardness tests, was suggested to be suitable for describing the load-dependence of the nanohardness. By comparing the best-fit values of the parameters included in this empirical relationship, the origin of the load-dependence of nanohardness was analyzed briefly.
