The analysis of nanoindentation data involves several steps:
1. Load-Displacement Curve: The primary data is a plot of the applied load versus the penetration depth. 2. Unloading Curve Analysis: The unloading portion of the curve is used to determine the elastic modulus. 3. Hardness Calculation: Hardness is calculated by dividing the maximum load by the contact area at maximum load. 4. Model Fitting: Advanced models may be used to fit the data and extract additional properties such as creep, and viscoelasticity.
