). As expected,
the higher strain amplitude leads to greater solute uptake enhancement, while 0.5%
amplitude produces near zero effect. The rise of enhancement of accumulation with
amplitude appears to be most pronounced for unbound solute. Following studies [10,
15], it may be hypothesized that amplitudes larger than 5% will enhance solute trans-
port even more. Unfortunately it is not possible to use the current model to investigate
larger amplitudes, because it is derived from the assumptions (2), (5), (6) and uses
continuum mechanics theory for in¿ nitesimal strains.
