A true triaxial strength criterion for rocks by gene expression programming
Journal of Rock Mechanics and Geotechnical Engineering, 2023 Rock strength is a crucial factor to consider when designing and constructing underground projects. This study utilizes a gene expression programming (GEP) algorithm-based model to predict the true triaxial strength of rocks, taking into account the ...

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 ...
