Figure 11.

Comparison of predicted and ‘experimental’ indentation responses for Se. The associated values of $n$, ${\sigma }_0$, ${\dot{ϵ}}_0$ and $\alpha$ are obtained from noise-contaminated HTS data (averaged over 100 realizations) and given in table 5. (a) Normalized indentation depth $h/h_{\mathrm{ela},\mathrm{Se}}$ versus normalized time $t/t_{\mathrm{ref},\mathrm{Se}}$. (b) Surface profiles near the indenter after unloading. (c) ${\log }_{10}$–${\log }_{10}$ plot of (a). On the scales in this figure, the predictions with ${\eta }_{\mathrm{h}}={\eta }_{\mathrm{s}}=0.01$ are indistinguishable from the corresponding ‘experimental’ responses.
