Deformation and failure of ice under constant stress or constant strain-rate
Malcolm Mellor,David M. Cole +1 more
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%.

Review of dry snow slab avalanche release
TL;DR: In this paper, the role of deficit zones in dry snow slab avalanche release is discussed, and a range of values on the size of these zones are given, typically between 0.1 to 10 m.

A theory of the fracture of metals
TL;DR: In this paper, a theory of the fracture of metals is presented, which is based on the theory of fracture theory of metal fracture, and it is proved that the theory is correct.

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.

The process of failure of columnar-grained ice
TL;DR: In this article, the authors reported on the cracking activity during compressive creep of columnar-grained ice with the axis of hexagonal symmetry of each grain tending to lie in the plane perpendicular to its long direction.
