Influence of Oscillation Amplitudes on Nanoindentation

Nanoindentation testing with continuous stiffness measurement (CSM) provides a rapid, local method for investigating mechanical properties as a function of penetration depth.

This is frequently accomplished by a fixed displacement amplitude of 2 nm. However, at small depths this amplitude can impose large effects on the measurement due to its relative magnitude. In this application note, we explore the relationship between oscillation amplitudes with fixed amplitudes in load and displacement, and we demonstrate that
proportionally-scaled amplitude ratio CSM modes provide superior results over all depths.
