Erratum — Determination of the true projected contact area by in situ indentation testing

The Original Article is available

Dr. Laetitia Phillippe’s name was misspelled. The misspelling has since been corrected.

In the abstract, the fourth sentence should have read: “The in situ projected contact area measured by Scanning Electron Microscopy using a cube-corner tip differs significantly from the classical models for materials with low H/E modulus ratio.” The abstract has since been corrected.

The label in Figure 8(b) has been corrected and appears below.


On page 2861, first column, the reference citation for sentence “Finally, let us note that numerical simulations were also used to estimate the true projected contact area” should be “[12, 13, 26]”.

On page 2866, second column, the sentence beginning “The projected contact area at maximum load…” should refer to the section “Method to calculate the in situ contact area”.

Reference 25 should not have been included. In-text citations to reference 25 should be to reference 12.

The publisher apologizes for these errors.
