Fit of RVE Model to Stress Relaxation Data
||There is good fit between RVE model predictions (red) and data (blue) only in the strain range of pure viscoelasticity. |
At higher strain (left) the tissue is not fully preconditioned - the response is not pure viscoelastic.
Magnified view of the RVE model-to-data fit in the pure viscoelastic strain range.
Left – the entire test protocol.
Right - the step response.
Lines of model prediction (red) and data (blue) are visibly indistinguishable.
