Abstract

The measurement methods of area function that are commonly used in nanoindentation are summarized and analyzed. An area function determination method based on the geometry of indenter tip for very small indentation depth is proposed. It combines the advantages of the area function measurement method based on measurement of standard sample and that based on indenter geometry. Experiments have been carried out to examine the effect of the area function. It is shown that this area function measurement method can improve the measurement accuracy of indentation hardness and reduced modulus when the indentation depth is very small.
