Further Insight into the Depth-Dependent Microstructural Response of Cartilage to Compression Using a Channel Indentation Technique
Figure 9
Images of the channel relief zone from a sample tested at the high strain level. (a) Obliquely directed shear bands (dotted line). White arrows in (a) indicate matrix “flow lines” originating from the adjacent directly loaded regions. (b) Smaller dotted lines highlight a transverse directionality to minor compression bands formed within the oblique shear bands (dashed line). (c) shows in greater detail the features of the minor bands within the larger shear bands. Arrows indicate an in-phase fibrillar crimping from which the transversely directed minor bands (highlighted with the small dotted line) are derived. (d) Arrows point to chondrocyte distortion within the transverse bands.
