Description¶
The material type for an exponential weak bond recruitment function is recruitment exponential.
For this material the recruitment function is given by,
\[
F\left(\Xi\right)=\mu_{0}\exp\left(\mu_{1}\left(\frac{\Xi}{s}\right)^{\alpha}\right)
\]
where \(\Xi\) is the measure of strain that triggers a new reactive weak bond generation. This function is unbounded with increasing \(\Xi\). Users should typically employ \(\mu_{0}=1\).
