Power law slip rule defined as \(\dot{\gamma}_i = \dot{\gamma}_0 \left| \frac{\tau_i}{\hat{\tau}_i} \right|^{n-1} \frac{\tau_i}{\hat{\tau}_i}\) with \(\dot{\gamma}_i\) the slip rate on system \(i\), \(\tau_i\) the resolved shear, \(\hat{\tau}_i\) the slip system strength, \(n\) the rate senstivity, and \(\dot{\gamma}_0\) a reference slip rate.
