Deformation and failure of ice under constant stress or constant strain-rate

TL;DR: In this paper, a fine-grained isotropic ice was tested in uniaxial compression at −5°C. Tests were made under: (1) constant strain rate, and (2) constant stress, with total axial strains up to about 7%.

Mechanism of creep in brittle rock

TL;DR: In this article, a review of the experimental evidence suggests that creep in brittle rock at low temperature is due to time-dependent cracking, and a transient creep law is derived from the mechanism of timedependent cracking in an inhomogeneous brittle material, described as a Markov process with a stationary transition probability that is obtained from experimental observations of static fatigue in glasses.
