Experimental investigation on mechanical properties and permeability evolution of red sandstone after heat treatments
TL;DR: In this paper, a triaxial compression test was carried out on red sandstone samples which had been previously subjected to heat treatments at 20, 200, 400, and 600 °C to study the change in properties and mechanical characteristics of the rock and the permeability evolution.
Triaxial test research on mechanical properties and permeability of sandstone with a single joint filled with gypsum
TL;DR: In this paper, the authors investigated the mechanical properties and permeability variation in single joint rock samples filled with a gypsum layer, and found that the peak strength and failure modes change with the inclined angles.

Effect of Confining Pressure on the Damage Evolution and Failure Behaviors of Intact Sandstone Samples During Cyclic Disturbance
TL;DR: In this paper, the effect of confining pressure on the damage evolution and failure behaviors of intact sandstone samples during cyclic disturbance was investigated, and the mechanism of the sudden jump in stress at the end of cyclic disturbances was analyzed based on the cusp catastrophe theory and a proposed mechanical model for the rock-test machine system.
