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.

Plasticity Model for Hybrid Fiber-Reinforced Concrete under True Triaxial Compression [PDF]
Journal of Engineering Mechanics, 2014 Based on the experimental background of 75 true triaxial compression tests conducted on cubic specimens, a plasticity constitutive model for hybrid steel-polypropylene fiber-RC (HFRC) is developed in this study, aiming to accurately predict the strength and deformation of HFRC under various loading scenarios.
