Abstract

Through parametric finite element calculations of the contact problem in nanoindentation we developed a series of semi-analytical functions that describe the inverse relationship between nanoindentation force-displacement data and the underlying materials stress-strain curves. We applied the method successfully to determine stress-strain curves of MEMS parts and to quantify strain hardening around fibers in metal matrix composites.
