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.
