Despite its numerous advantages, nanoindentation also presents several challenges:
Surface Preparation: A smooth, clean surface is essential for accurate measurements, which can be difficult to achieve, especially for certain types of nanomaterials. Measurement Sensitivity: The technique is highly sensitive to factors such as thermal drift and instrument compliance, which need to be carefully controlled to ensure precise results. Data Interpretation: Analyzing the load-displacement curves to extract meaningful mechanical properties requires a deep understanding of the material behavior and sophisticated data processing techniques.
