SlipSingleHardening¶

Overview¶

This object degenerates the general SlipHardening model so that all slip groups and systems share the same scalar slip system strength. The actual internal variables remain generic.

This produces the interface

$\bar{\tau}, \frac{\partial \bar{\tau}}{\partial \mathbf{h}} \leftarrow \mathcal{T}\left(\mathbf{h}, \bm{\alpha}, T \right) \dot{\mathbf{h}}, \frac{\partial \dot{\mathbf{h}}}{\partial \bm{\sigma}}, \frac{\partial \dot{\mathbf{h}}}{\partial \mathbf{h}} \leftarrow \mathcal{H}\left(\bm{\sigma}, \mathbf{h}, \bm{\alpha}, T \right)$

where $\bar{\tau}$ is now a single scalar.
