Size Effect and Anisotropy in a Transversely Isotropic Rock Under Compressive Conditions

A series of uniaxial and triaxial compression tests were performed on slate samples with different diameters at different foliation orientations with respect to the direction of the major principal stress. The size effect and anisotropy in slate, as a transversely isotropic rock, were investigated, and the research focused on aspects of elastic properties, uniaxial compressive strength (UCS), triaxial compressive strength (TCS), and triaxial...
