From: Enzymatic digestion of articular cartilage results in viscoelasticity changes that are consistent with polymer dynamics mechanisms

Figure 6

Phase lag data suggest flow-independent processes. The phase lag data suggest that cyclical loading experiments probed flow-independent processes after 1 day of digestion. Previous research [9, 10] suggests that flow-dependent viscoelasticity is frequency-dependent with substantial dissipation, as measured by the cyclical loading phase lag between the applied displacement and the measured stress, between 10-6 and 10-1 Hz. The present cyclical loading data found substantial dissipation at frequencies of 10-2 Hz and higher, indicating that these data represent flow-independent processes.
