... A computerized, servohydraulic test system has been used in the laboratory to perform axisymmetric, triaxial compression tests on natural rock salt using a load path that maintains constant mean stress. The constant mean stress test protocol illustrates that modern test systems allow...

... 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...

... Measurements of steady state creep rates and activation parameters are described for rock salt at low temperature ( T ≤ 0.4 T m ; where T m is melting temperature) and low strain rates. The determinations of steady state creep rates rely on the evaluation of upper and lower bounds...
