Abstract

A constitutive law for natural rock salt is given that describes the relationship among strain rate, stress rate, stress, temperature, and time. Tests required to evaluate the constitutive parameters are identified, and procedures for performing these tests are described. Results are presented from a series of tests performed on bedded salt from the Palo Duro basin. These results are used to evaluate the constitutive parameters, yielding a constitutive law suitable for predicting stresses and deformations in a nuclear waste repository or other engineered structure in salt.
