Constitutive models applied in the analysis of creep of rock salt

Technical Report ·
DOI:https://doi.org/10.2172/6034926· OSTI ID:6034926
constitutive equations for the creep of rock salt that have been utilized in the analyses of salt deformations are summarized. Primary creep, secondary creep, and elastoviscoplastic models are discussed. The strains predicted by several of the primary creep constitutive models are compared for identical conditions of deviatoric stress and temperature. Steady-state creep rates are compared under identical conditions of deviatoric stress and temperature for the secondary creep equations. 4 tables.
