Figure 28.

Comparison of experimental stress–strain curves and model predictions at $\dot{\epsilon }=0.0025\%/\mathrm{s}$ and ${\epsilon }_{\mathrm{a}}=0.05\%$. ($\epsilon (\%)$ is strain, $\sigma$ (MPa) is stress, $\dot{\epsilon }(\%/s)$ is strain rate, ${\epsilon }_{\mathrm{a}}(\%)$ is strain amplitude, the fitting curve is red and the experiment data is black.).
