Influence of principal stress effect on deformation and permeability of coal containing beddings under true triaxial stress conditions [PDF]
Royal Society Open Science, 2019 In situ stress is generally an anisotropic/true triaxial stress (σ1 > σ2 > σ3). Bedding weakens the continuity and integrity of coal. It is critical to understand the mechanical behaviour and gas migration of coal under true triaxial stress conditions ...

Failure properties of rocks in true triaxial unloading compressive test
Transactions of Nonferrous Metals Society of China, 2015 Slabbing failure often occurs in the surround rock near a deep underground excavation. The mechanism of slabbing failure is still unclear. In order to reveal the influence of the intermediate principal stress (σ2) on slabbing failure, true triaxial unloading compressive test was carried out based on the stress path of the underground engineering ...
