Post-peak Stress–Strain curves of brittle hard rocks under axial-strain-controlled loading

A super stiff rock mechanics testing machine called Stiffman is introduced in this paper. This test facility uses composite loading frames and relay loading by two loading hydraulic actuators and overcomes the technical difficulties of conventional rock mechanics testing machines such as insufficien...
