Abstract

The sensitivity of modulus measured by traceably calibrated Depth Sensing Indentation (DSI) is investigated as a function of the indentation parameters: maximum load; loading rate; hold time at maximum load; and single vs. repeated loading. Other issues, including instrument compliance, indenter area function and in-plane anisotropy are also discussed.
