Figure 6

Nanoindentation of Haliotis shell sectioned in orientation B. Nanoindentation experiments performed on a polished section in orientation B. Hardness (A) and Young's modulus (B) are shown as a function of indentation position. C, Scanning electron microscopy image of the cross section after the experiments. The positions of some indents with respect to the 20 μm super-structure are exposed. Indents were 20 μm apart from each other and do not exactly match with the periodicity of the super-structure. Note that the super-structure in this image was visualized at a tilt angle of 20°.
