emoved the oscillations partially and is indeed more representative of the true
configuration of the transition between the two IVD sub-tissues.
The results suggest that most of the existing spine poromechanical models are not
suitable to locally simulate the effect of physiological loading rates. Nonetheless,
provided that mesh convergence has been properly assessed through poromechanical
predictions, 30 minutes of load relaxation could be sufficient for these instabilities to
disappear. This time frame is inferior to that found in the previous studies using
poroelastic models mechanically loaded for more than one hour (Schroeder et al., 2007
Malandrino et al., 2011).
