Further Insight into the Depth-Dependent Microstructural Response of Cartilage to Compression Using a Channel Indentation Technique
Figure 3
Typical stress relaxation curve obtained for a medium strain level compression test showing the viscous and elastic regions. The viscous response refers to the initial rapid stress decay, and the elastic response refers to the latter portion of the curve. The table inset summarises the parameters obtained from the curve fits from applying the Maxwell-body model to each region of the stress relaxation curve for the different strain levels tested. The criterion for each fit was .
