out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force. The tensile strength is then calculated as the failure tensile force divided by the cross-sectional area. It has been found that a rock core will split along a diameter when loaded on its side in a compression machine.
