Correcting for contact area changes in nanoindentation using surface acoustic waves

Abstract:

Nanoindentation is extensively used to quantify nano-scale mechanical behaviour. A widely-used assumption is that a well-defined, materialindependent relationship exists between the indentation depth and indenter contact area. Here we demonstrate that this assumption is violated by ionimplanted tungsten, where pileup around the indenter tip leads to substantial changes in contact area. Using high accuracy surface acoustic wave measurements of elastic modulus, we are able to correct for this e...
