QLV and Adaptive QLV models were both suitable when compared against these
data. An additional single, large amplitude ramp-and-hold test performed at a
different loading rate showed that, for this particular tissue, both models provided
suitable predictions. However, minor differences in the two model predictions
were also evident, and careful study would be needed to determine model suit-
ability for loading rates outside of those tested.
In summary, the Adaptive QLV model provides a simple-to-fit nonlinear
alternative to the Fung and Generalized Fung QLV models. Because each of these
three models rests upon a set of assumptions, application of any of these models to
a particular tissue requires careful testing over the range of strains and strain rates
that are of interest for a particular application.
