Comparison of transient deformation predicted by our model to experimental data. Plastic strain as a function of time from a stress-reduction experiment (OxR0002) from Hansen et al. (6) (black line) compared to the model prediction (red line). This experiment was performed on a single crystal compressed uniaxially in the [101]_c orientation at 1,523 K. The initial stress prior to reduction was 162 MPa. The curves are labeled with the percentage reduction in stress. In A, the plastic strain rate evolves over relatively short timescales (∼10 s), whereas in B, the plastic strain rate evolves over longer timescales (∼100 s).
