Figure 6.

Comparison of predicted and ‘experimental’ indentation responses for ${\mathrm{CsHSO}}_4$. The indentation responses are those corresponding to the largest value of posterior probability for the indentation depth versus time data (HT), for the residual surface profile data (S) and for both the indentation depth versus time data and the residual surface profile data (HTS). The associated values of $n$, ${\sigma }_0$, ${\dot{ϵ}}_0$ and $\alpha$ are given in table 3. (a) Normalized indentation depth $h/h_{\mathrm{ela},{\mathrm{CsHSO}}_4}$ versus normalized time $t/t_{\mathrm{ref},{\mathrm{CsHSO}}_4}$ where $t_{\mathrm{ref},{\mathrm{CsHSO}}_4}=1/{\dot{ϵ}}_{0,{\mathrm{CsHSO}}_4}$. (b) Normalized surface profiles, $z/h_{\mathrm{ela},{\mathrm{CsHSO}}_4}$ versus $r/h_{\mathrm{ela},{\mathrm{CsHSO}}_4}$, near the indenter after unloading. (c) ${\log }_{10}$–${\log }_{10}$ plot of (a). On the scales in this figure, the predictions with S and HTS data are indistinguishable from the corresponding ‘experimental’ responses.
