... ppi to 90 ppi and strain rates varying from 2.5 × 10 − 3 to 10 1 s − 1 well. The full model can also be well approximated by a simpler model, based on the lubrication approximation, which is applicable to analyses where the dimension of the foam in the direction of fluid flow (radial) is much greater...
