The effects of water content, temperature and loading rate on strength and failure process of frozen rocks
TLDR
In this paper, the effects of water content, temperature and loading rate on the strength and failure process of rock at sub-zero temperatures were investigated and the results showed that the presence of water in the rock resulted in a marked increase in rock strength and fracture initiation stress.About:

Mechanical and Acoustic Emission Characteristics of Coal at Temperature Impact
TL;DR: In this article, the authors investigated the influence of temperature impact on the mechanical properties and acoustic emission (AE) characteristics of coal and found that temperature impact causes the development of pores and cracks in the coal, which reduces the strength of coal.

Fractal characteristics and acoustic emission of anisotropic shale in Brazilian tests
TL;DR: In this article, the tensile strength and acoustic emission of shale were investigated at various orientations of the laminations with respect to the loading direction, and the results showed that fractal dimension values fluctuate with increase of the stress, signifying the initiation of complex microcracks within the shale.

Influence of Pore Water (Ice) Content on the Strength and Deformability of Frozen Argillaceous Siltstone
TL;DR: Fan et al. as discussed by the authors investigated the influence of the initial water content on the mechanical properties of frozen argillaceous siltstone (at − 20 °C) and found that the initial tangent modulus of the Siltstone exhibits a significant increase with decreasing temperature.
