Uniaxial creep and stress relaxation responses using the averaged predicted parameter values over 100 realizations for Se obtained with noise-contaminated HTS data in table 5. The solid lines show the corresponding ‘experimental’ responses. (a) Uniaxial logarithmic strain, $ϵ$, versus time $t$. (b) Normalized uniaxial Cauchy stress, $\sigma /E$, versus time, $t$. On the scales in (a), the prediction with ${\eta }_{\mathrm{h}}={\eta }_{\mathrm{s}}=0.01$ is indistinguishable from the corresponding ‘experimental’ response. In (b), the prediction with ${\eta }_{\mathrm{h}}={\eta }_{\mathrm{s}}=0.01$ is indistinguishable from the prediction with ${\eta }_{\mathrm{h}}={\eta }_{\mathrm{s}}=0.10$.
