## Abstract The discretization in time of the initial boundary value problem for rate‐dependent (elastic‐viscoplastic) solid materials in presence of softening is investigated in this paper. The emphasis is put on uniqueness, loss of ellipticity and localization. It is found that the time‐discretiz
