Further Insight into the Depth-Dependent Microstructural Response of Cartilage to Compression Using a Channel Indentation Technique
Figure 7
Bulge development resulting from the channel relief zone in the indenter (outlined in grey) between the two directly loaded regions (P). Macroimages (a), (b), and (c) show typical indentation profiles of samples compressed to low, medium, and high levels of strain. The bold and dotted lines on the right gauge the undeformed and deformed thicknesses, respectively, of each of the sections shown. In the boxed inset the dotted lines are shown side-by-side to illustrate the relative differences in the low, medium, and high strain levels in the directly loaded regions.
