Abstract: The results of creep and cyclic loading experiments on laboratory-prepared saline ice specimens are presented, and a method is developed to calculate an effective mobile dislocation density for ice specimens based on their cyclic loading response. This method provides a means to track increases in the dislocation density, and thus anelastic compliance, that occur during creep straining. An expression for the stress and strain dependence of the dislocation density is presented and shown to be in good agreement with the experimental findings.
