Detailed Description
Hertz potential.
This is a repulsive potential, that for example, describes the change in elastic energy of two deformable objects when subjected to an axial compression.
\[ u(r) = \epsilon \left(1 - \frac{r}{\sigma}\right)^{5/2} \]
where r_H corresponds to the particle's radius.
