In the MVIB model, the Green strain tensor is decomposed into spherical and deviatoric parts and the stretch deformation of bonds are decomposed into spherical dilatational deformation and deviatoric deformation to calculate bonds' strain energy.
In such a confined geometry, these films experience large compressional or dilatational strain that may be detrimental to their long term stability, thus damaging the materials.
Thus, the higher velocity consistently found in trees compared with logs during previous research is coherent, because the velocity is stiffness dependent and the dilatational wave velocities of trees are greater than the one-dimensional wave velocity of logs (Wang 2013).

6] So-called noncompliant balloons were exclusively used in our study; they are characterised by the fact that they only change their diameter minimally upon dilatational pressure and therefore minimise the risk of overexpansion.
These holes, called dilatational bands, function as a natural defense mechanism, and help to prevent further damage to the surrounding bone.
