[240] Indenter Tip Wear Effects in Nanoindentation with Continuous Stiffness Measurement

Indenter tip wear affects area function and edge behavior, causing modulus and hardness deviations. Enhanced calibration corrects area function errors. Bulk-equivalent hardness is unaffected by tip wear and ISE, providing a reliable measurement alternative.
