Effects of assumed pressure distributions on the fundamental relation used in nanoindentation data analysis
This short note shows that contact stiffness under a non-Hertzian pressure distribution is 33% higher than that under a Hertzian pressure distribution. This is due to the fact that there is no physical indenter that gives a non-Hertzian pressure distribution during elastic contact, and the fundamental relation used in nanoindentation data analysis does not apply.
