Nanoindentation

Load–depth curves and instrument array summaries. Unloading fits use explicit contact-area and geometry assumptions; instrument-reported values remain separate.

Ready to start

Input Requirements & Procedure

Required Inputs:

•Tab-separated load–depth export with depth in nm, load in µN and time in s, or a supported NSS array table.
•Unloading fit window, tip geometry factor and any measured depth/drift corrections.
•Optional calibrated projected contact area and sample Poisson ratio.

Operating Instructions:

Choose Nanoindentation and load your file or the synthetic example.
For curves, review the unloading window and calibration assumptions before calculating. Curve controls do not alter instrument-reported array values.
Inspect the measured curve, fitted unloading segment, fit quality and warnings; export the results.

Scientific Scope & Limitations

⚠️The default contact area is an ideal Berkovich estimate, not an instrument calibration. Instrument-reported and fitted results can differ.
⚠️Pile-up, substrate effects, viscoelasticity and frame compliance are not corrected automatically. Validate load/displacement calibration.
⚠️Sample Young’s modulus is reported only when a sample Poisson ratio is supplied. Reduced modulus is a different quantity.
⚠️Array statistics retain all rows and use sample standard deviation. Multi-cycle curves require separate analysis.
