Exponential-time creep law for Avery Island salt
Triaxial compression creep data previously collected for specimens of dome salt from Avery Island, Louisiana were fitted to an exponential-time creep law. An exponential-time law was used because it has been identified as the baseline creep law to be used for salt in the National Waste Terminal Storage Program. Fits to the data reveal the creep law is bi-modal in that two expressions for the stress and temperature dependence are obtained for some parameters: one for low steady-state strain rates and one for high steady-state strain rates. As a result, a critical steady-state strain rate value was determined to separate the high and low strain rate regions. Subsequently, data within each region were used to obtain quantitative values for the two creep-law expressions.
