The Young’s modulus measured with micro-indentation before (left of dashed line) or after (right) SAOS did not affect the measured sample modulus. SAOS samples could be tested once (N = 1), while micro-indentation samples were indented multiple times (N = 3) to obtain the mean and standard deviation.
