Influence of $e_{\min }$ on the creep response of a linearly viscoelastic material, using n = 256 time steps: (a) number of generations m, (b) relative error between numerical response and analytical solution of Eq. (3.2), and (c) the creep strain response when $e_{\min }={10}^{-5}$ (one-tenth of the equilibrium strain ${10}^{-4}$) shows unacceptable deviations from the analytical solution, while lower values of $e_{\min }$ (one-hundredth or lower) produce more acceptable agreements
