Includes test data from Confined Brazilian Tests. The tests were aim at investigating the rock failure envelope of four different lithologies including Indiana limestone, Scioto sandstone, Grey Berea sandstone, and Tennessee sandstone. Tables include the strength data obtained using load and damage controlled Brazilian tests on the six lithologies. Confine Brazilian tests are preformed by wrapping a sample in a copper jacket so that the confining fluid does not directly interact with the sample. Then a constant confining pressure is applied to the fluid to create a state of triaxial stress in the disc such that the disc center is under three nonzero and unequal principal stress components. By increasing the confining pressure, the least principal stress changes from tensile to compressive so that rock failure can be investigated over a wide range of stress conditions.
