New Tools to solve known problems at critical nanoindentation measurements
October 1-6, 2017
The nanoindentation measurement process is a widely used in material science. It delivers very useful information about the mechanical properties with high spatial resolution. Nevertheless the knowledge of the exact contact mechanic with its geometrical conditions of indenter tip and sample surface in the contact area is essential for the accuracy of the results.
Because the indenter geometry is not free of tolerances as well the sample surface is not in the accurate position to the indenter – so corrections are necessary to solve this incorrectness. The detailed analysis of flat punch force-displacement curves allows to correct the incorrectness of the contact surfaces by aligning the sample surface parallel to the real flat punch surface.
