Anisotropic characteristics and creep model for thin-layered rock under true triaxial compression
Journal of Rock Mechanics and Geotechnical EngineeringThe failure phenomenon of thin-layered rock tunnels not only exhibits asymmetric spatial characteristics, but also significant time-dependent characteristics under high in-situ stress, which is attributed to the time-dependent fracture of thin-layered ...

Influence of end effect on rock strength in true triaxial compression test [PDF]
Canadian Geotechnical Journal, 2017 The influence of the end effect on rock strength in true triaxial compression testing was studied using a numerical approach. The influence of the intermediate principal stress (σ2) on rock strength was isolated by using the two-dimensional Mohr–Coulomb failure criterion that depends only on the major principal stress (σ1) and minor principal stress ...

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 ...

Strength behavior of plain cement concrete subjected to true triaxial compression [PDF]
Canadian Journal of Civil Engineering, 2018 True triaxial compression test was conducted on 100 mm × 100 mm × 100 mm cubical sample of plain cement concrete using the true triaxial testing machine. A total of 30 tests were conducted on two concrete mixes having characteristic strengths of 24.39 MPa and 34.67 MPa.
