volume strain can be neglected. For saturated soils the result is an insignificant
variation of the interstitial pressure, and therefore deterioration of properties is
absent.
To conclude, within this strain range, soil behavior is definitely non-linear,
though it stays markedly elastic because the permanent changes in its microstructure
are negligible.
