A notable feature of replicated creep and creep-rupture data is the considerable amount of statistical scatter present. The existence of this scatter leads to substantial uncertainties in the predictions of creep deformation and failure. In this paper, we review the experimental evidence in this regard. We then survey recent efforts to construct models of creep deformation and rupture that include one or more aspects of this randomness. [S0094-4289(00)01703-5]
