Description¶
The material type for a polynomial weak bond recruitment function is recruitment polynomial.
For this material the recruitment function is given by
\[
F\left(\Xi\right)=\mu_{0}+\mu_{1}\Xi+\mu_{2}\Xi^{2}
\]
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 \(\mu_{0}=1\).
Example:
<recruitment type="recruitment poly">
<mu0>1</mu0>
<mu1>0</mu1>
<mu3>50</mu3>
</recruitment>
