Description¶
The experimental spring is a discrete element material that has the following force-displacement function,
\[
f\left( d \right)=\left\{ \begin{matrix}
{{s}_{M}}\left( 1-\exp \left( -E\,d/{{s}_{M}} \right) \right),\quad d\ge 0 \\
-{{s}_{m}}\left( 1-\exp \left( -E\,d/{{s}_{m}} \right) \right),\quad d<0 \\
\end{matrix} \right.
