Deformation and Failure Characteristics of Three Sandstone Types Under True Triaxial Stress With a Fixed Lateral Stress Difference
This study conducts true triaxial compression tests on three types of sandstone under a constant intermediate principal stress of σ 2 = 28 MPa. The stresses applied to the X ‐direction surfaces are progressively increased while their difference remains fixed at Δ σ = 3 MPa. Strength, deformation, failure m...
